THE OFFER, PRORATION PERIOD AND WITHDRAWAL RIGHTS WILL EXPIRE AT
5:00 P.M., NEW YORK CITY TIME, ON WEDNESDAY, MAY 16, 2018 UNLESS THE OFFER IS EXTENDED (SUCH DATE AND TIME, AS THEY MAY BE EXTENDED, THE EXPIRATION TIME).

This offer is being made by Herbalife Ltd., a Cayman Islands exempted company incorporated with limited liability (the Company,
we, or us). We are offering to purchase common shares, par value $0.001 per share in the capital, of the Company (the common shares or shares) for an aggregate cash purchase price of up to $600 million
and at a per share price not greater than $108.00 nor less than $98.00, net to the seller in cash, less any applicable tax withholding and without interest, and as adjusted for any stock split, upon the terms and subject to the conditions described
in this Offer to Purchase (which may be amended and supplemented from time to time, the Offer to Purchase) and the related Letter of Transmittal (the Letter of Transmittal) (which together, as they may be amended and
supplemented from time to time, constitute the Offer).

Upon the terms and subject to the conditions of the Offer, the Company
will purchase common shares properly tendered and not properly withdrawn for an aggregate Cash Purchase Price (as such term is defined below) of up to $600 million, constituting approximately 6.9% of the total number of outstanding common shares as
of the close of trading on April 16, 2018 (assuming the Company acquires common shares pursuant to this Offer at the lowest possible Cash Purchase Price of $98.00 per share, as adjusted for any stock split). Unless the context otherwise
requires, all references to shares shall refer to the common shares and all references to shares properly tendered shall refer to shares properly tendered and not properly withdrawn in the Offer.

Upon the terms and subject to the conditions of the Offer, promptly following the Expiration Time, we will determine a single per share price,
which will be not greater than $108.00 nor less than $98.00 per share, net to the seller in cash (the Cash Purchase Price), less any applicable tax withholding and without interest, and as adjusted for any stock split, that we will pay
for those shares properly tendered for an aggregate Cash Purchase Price of up to $600 million. The Cash Purchase Price will be the lowest price per share not greater than $108.00 nor less than $98.00 per share (in multiples of $0.25), as adjusted
for any stock split. at which shares have been properly tendered in the Offer that will enable us to purchase the maximum number of shares for an aggregate Cash Purchase Price of up to $600 million. If fewer than such number of shares as would
enable us to purchase shares pursuant to the Offer for an aggregate Cash Purchase Price of up to $600 million are properly tendered, we will select the lowest price that will allow us to purchase all the shares that are properly tendered. We reserve
the right, in our sole discretion, to change the per share purchase price range and to increase or decrease the value of shares sought in the Offer, subject to applicable law. In accordance with the rules of the Securities and Exchange Commission
(the SEC), we may increase the number of shares accepted for payment in the Offer by no more than 2% of the outstanding shares without extending the Offer. See Section 1.

All shares we purchase in the Offer will be purchased at the same Cash Purchase Price, regardless of whether the shareholder tendered, or was
deemed to have tendered, at a lower cash price. We will not purchase any shares from shareholders that do not properly tender any of their common shares pursuant to the Offer prior to the Expiration Time. If our purchase of all shares properly
tendered at or below the Cash Purchase Price and not properly withdrawn in the Offer would result in an aggregate Cash Purchase Price of more than $600 million, we will purchase all shares properly tendered at or

below the Cash Purchase Price on a pro rata basis, except for odd lots (lots held by owners of less than 100 shares at the Expiration Time), which we will purchase on a priority
basis, and except for each conditional tender whose condition was not met, which we will not purchase. Tendering shareholders will receive a cash payment only if their tendered shares are purchased. Shares properly tendered but not purchased
pursuant to the Offer will be returned to the tendering shareholders at our expense promptly after the Offer expires. See Section 3.

The number of common shares subject to the Offer and the price per share relate to the common shares as outstanding on the date of the
Offer. The Expiration Time is currently scheduled two days after the stock split distribution date (May 14, 2018), when the Company expects to effect a two-for-one stock split as described in the Companys 2018 proxy statement. Following the
stock split, the Cash Purchase Price will be adjusted ratably to account for the increased number of common shares outstanding on a post-split basis. See Section 8.

The Offer is not conditioned upon the receipt of financing. The Offer is, however, subject to certain other conditions. See Section 7.

As of April 16, 2018, there were 88,202,525 common shares outstanding. The shares are quoted on the New York Stock Exchange (the
NYSE) under the symbol HLF. On April 17, 2018, the last full trading day before we commenced the Offer, the reported closing price of the shares on the NYSE was $103.02 per share, which is greater than the low end of the
price range for the Cash Purchase Price of $98.00 per share. Shareholders are urged to obtain current market quotations for the shares. See Section 8.

The Board of Directors of the Company (the Board) has unanimously approved the Offer pursuant to the recommendation of a
committee of the Board, which is comprised solely of individuals, each of whom the Board has determined to be an independent director under Section 303A.02 of the NYSE Listed Company Manual (the Committee). However, none of the
Board, the Committee, the Company, Computershare Trust Company, N.A., the depositary and paying agent for the Offer (the Depositary and Paying Agent), or Georgeson LLC, the information agent for the Offer (the Information
Agent), is making any recommendation to you as to whether to tender or refrain from tendering your shares or as to the purchase price or purchase prices at which you may choose to tender your shares. You must make your own decision as to
whether to tender your shares and, if so, how many shares to tender and the price or prices at which you will tender them. In doing so, you should read carefully the information in this Offer to Purchase and in the related Letter of Transmittal,
including our reasons for making the Offer. None of the directors or executive officers of the Company intend to tender any of their shares in the Offer. See Sections 2 and 11.

(1) (a) if you hold certificates in your own name, complete and sign the Letter of Transmittal in accordance with the
instructions to the Letter of Transmittal, have your signature on the Letter of Transmittal guaranteed if Instruction 1 to the Letter of Transmittal so requires, and mail or deliver the Letter of Transmittal, together with any other required

tendering shares.

box in the section of the Letter of Transmittal captioned Shares Tendered at Cash Price Determined Under the Offer. If you agree to accept the Cash Purchase Price determined in the Offer, your shares will be deemed to be tendered at the
minimum price of $98.00 per share. Checking the box captioned Shares Tendered at Cash Price Determined Under the Offer will increase the possibility that the Cash Purchase Price will be set at $98.00 per share.

of this Offer to Purchase. Requests for additional copies of this Offer to Purchase or the related Letter of Transmittal may be directed to the Information Agent.

shares in such state(s).

We have not authorized any person to make any recommendation on our behalf as to whether you should tender or
refrain from tendering your shares or as to the purchase price or purchase prices at which you may choose to tender your shares in the Offer. You should rely only on the information contained in this Offer to Purchase or to which we have referred

to Purchase, but you should realize that it does not describe all of the details of the Offer to the same extent described in this Offer to Purchase. We urge you to read the entire Offer to Purchase and the related Letter of Transmittal because they

Who is offering to purchase my shares?

This Offer is being made by Herbalife Ltd., a Cayman Islands exempted company incorporated with limited liability (the Company).

What is the Company offering to purchase?

We are offering to purchase common shares, par value $0.001 per share, of the Company (the common shares) for an aggregate Cash
Purchase Price of up to $600 million. See Section 1. Under the terms of the Offer, the Company, subject to the satisfaction or waiver of the terms and conditions of the Offer, will purchase common shares that were properly tendered (and not
properly withdrawn) pursuant to this Offer for an aggregate Cash Purchase Price of up to $600 million.

Why is the Company conducting a second tender
offer?

The Company believes that the repurchase of shares pursuant to the tender offer is consistent with its long-term goal of
maximizing shareholder value. The Board evaluated the Companys operations, financial condition, capital needs, regulatory requirements, strategy and expectations for the future and believes that the tender offer is a prudent use of the
Companys financial resources and determined that a tender offer is an appropriate mechanism to return capital to shareholders that seek liquidity under current market conditions and allowing shareholders who do not participate in the tender
offer to share in a higher portion of the Companys future potential.

What will the purchase price for the shares be and what will be the form of
payment?

We are conducting the Offer through a procedure commonly called a modified Dutch Auction. This procedure allows
you to select the cash purchase price (in multiples of $0.25) within a price range specified by us at which you are willing to sell your shares. The price range for the Offer is $98.00 to $108.00 per share. Upon the terms and subject to the
conditions of the Offer, promptly following the Expiration Time, we will determine a single per share price, which will be not greater than $108.00 nor less than $98.00 per share, net to the seller in cash (the Cash Purchase Price), less
any applicable tax withholding and without interest, and as adjusted for any stock split, that we will pay for shares properly tendered, for an aggregate Cash Purchase Price of up to $600 million.

The Cash Purchase Price will be the lowest price per share not greater than $108.00 nor less than $98.00 per share (in multiples of $0.25), as
adjusted for any stock split, at which shares have been properly tendered in the Offer that will enable us to purchase the maximum number of shares for an aggregate Cash Purchase Price of up to $600 million. If fewer than such number of shares as
would enable us to purchase shares pursuant to the Offer for an aggregate Cash Purchase Price of up to $600 million are properly tendered, we will select the lowest price that will allow us to buy all the shares that are properly tendered. All
shares we purchase will be purchased at the same Cash Purchase Price, even if you have tendered at a lower cash price (or are deemed to have tendered at a lower cash price), but we will not purchase any shares tendered above the Cash Purchase Price.
The Company will make a cash payment to tendering shareholders only if we have purchased their tendered shares. We will not

purchase any shares from shareholders that do not properly tender any of their common shares pursuant to the Offer prior to the Expiration Time.

If you wish to maximize the chance that your shares will be purchased, you should check the box of the section of the Letter of Transmittal
captioned Shares Tendered at Price Determined under the Offer indicating that you will accept the Cash Purchase Price. If you agree to accept the Cash Purchase Price determined in the Offer, your shares will be deemed to be tendered at
the minimum price of $98.00 per share. Checking the box captioned Shares Tendered at Cash Price Determined Under the Offer will increase the possibility that the Cash Purchase Price will be set at $98.00 per share.

If your shares are purchased in the Offer, for each such share, we will pay you the Cash Purchase Price in cash, less any applicable tax
withholding and without interest, and as adjusted for any stock split, promptly after the Offer expires. See Sections 1 and 5. Under no circumstances will we pay interest on the Cash Purchase Price, even if there is a delay in making payment.

The number of common shares subject to the Offer and the price per share relate to the common shares as outstanding on the date of the Offer.
The Expiration Time is currently scheduled two days after the stock split distribution date (May 14, 2018), when the Company expects to effect a two-for-one stock split as described in the Companys 2018 proxy statement. Following the stock
split, the Cash Purchase Price will be adjusted ratably to reflect the increased number of common shares outstanding on a post-split basis. See Section 8.

What is the recent market price of my shares?

On April 17, 2018, the last full trading day before we commenced the Offer, the reported closing price of the shares quoted on NYSE was
$103.02 per share, which is greater than the low end of the price range for the Offer of $98.00 per share. You are urged to obtain current market quotations for the shares before deciding whether and at what purchase price or purchase prices to
tender your shares. See Section 8.

How many shares will the Company purchase in the Offer?

This Offer is being made by the Company. Upon the terms and subject to the conditions of the Offer, the Company will purchase common shares
properly tendered and not properly withdrawn pursuant to the Offer for an aggregate Cash Purchase Price of up to $600 million. If fewer than such number of shares as would enable us to purchase shares pursuant to the Offer for an aggregate Cash
Purchase Price of up to $600 million are properly tendered, we will purchase all shares that are properly tendered. If our purchase of all shares properly tendered at or below the Cash Purchase Price and not properly withdrawn in the Offer would
result in an aggregate Cash Purchase Price of more than $600 million, we will purchase all shares properly tendered at or below the Cash Purchase Price on a pro rata basis, except for odd lots (lots held by owners of less than 100 shares
at the Expiration Time), which we will purchase on a priority basis, and except for each conditional tender whose condition was not met, which we will not purchase (except as described in Section 6). The Offer is subject to certain conditions
described below. See Section 7.

We expressly reserve the right, in our sole discretion, to change the per share purchase price range
and to increase or decrease the value of shares sought in the Offer, subject to applicable law. In accordance with the rules of the SEC, we may increase the number of shares accepted for payment in the Offer by no more than 2% of the outstanding
shares without extending the Offer. See Section 1.

How will the Company pay for the shares?

The maximum aggregate Cash Purchase Price the Company will pay to purchase common shares pursuant to the Offer is $600 million. The Company
anticipates that it will pay for such shares tendered from the proceeds from the $1,300.0 million term loan under its $1,450.0 million senior secured credit facility entered into on February 15, 2017 (the Credit Facility), cash on
hand, and/or drawings under its $150.0 million revolving credit facility.

Consummation of the Offer is not subject to any financing condition, but is subject to
certain other conditions. See Section 7.

How long do I have to tender my shares?

You may tender your shares until the Offer expires. The Offer will expire on May 16, 2018, at 5:00 p.m., New York City time, unless we
extend it. See Section 1. If a broker, dealer, commercial bank, trust company or other nominee holds your shares, it is likely the nominee has established an earlier deadline for you to act to instruct the nominee to accept the Offer on your
behalf. We urge you to contact the broker, dealer, commercial bank, trust company or other nominee to find out the nominees deadline.

Can the
Offer be extended, amended or terminated?

We may choose to extend the Offer at any time and for any reason, subject to applicable
laws. See Section 15. We cannot assure you that we will extend the Offer or indicate the length of any extension that we may provide. If we extend the Offer, we will delay the acceptance of any shares that have been tendered. We can amend the
Offer in our sole discretion at any time prior to the Expiration Time. We can also terminate the Offer at any time prior to the Expiration Time if the conditions set forth in Section 7 are not met. See Sections 7 and 15.

How will I be notified if you extend the Offer or amend the terms of the Offer?

If we extend the Offer, we will issue a press release announcing the extension and the new Expiration Time by 9:00 a.m., New York City time, on
the next business day after the previously scheduled Expiration Time. We will announce any amendment to the Offer by making a public announcement of the amendment. See Section 15.

What is the purpose of the Offer?

We
believe that the repurchase of shares pursuant to the Offer is consistent with our long-term goal of maximizing shareholder value. On April 12, 2018, the Board unanimously approved this Offer pursuant to the recommendation of the Committee. In
determining to proceed with the Offer, the Board evaluated the Companys operations, financial condition, capital needs, regulatory requirements, strategy and expectations for the future and believes that the Offer is a prudent use of the
Companys financial resources. The Board determined that a tender offer is an appropriate mechanism to return capital to shareholders that seek liquidity under current market conditions and to allow shareholders that do not participate in the
Offer to share in a higher portion of the Companys future potential.

We believe that purchasing the shares in the Offer represents
an attractive use of capital. We also believe that the modified Dutch Auction tender offer set forth in this Offer represents a mechanism to provide all of the shareholders of the Company with the opportunity to tender all or a portion
of their shares and, thereby, receive a return of their investment if they so elect. The Offer provides such shareholders (particularly those who, because of the size of their shareholdings, might not be able to sell their shares without potential
disruption to the share price) with an opportunity to obtain liquidity with respect to all or a portion of their shares without potential disruption to the share price or incurring brokers fees or commissions and other transaction costs
associated with open market sales. In addition, if we complete the Offer, shareholders that do not participate in the Offer will automatically increase their relative percentage ownership interest in the Company and its future operations at no
additional cost to them. Following the completion or termination of the Offer, we may, from time to time, make additional repurchases of shares, either in the open market, through public or privately negotiated transactions, in additional tender
offers, or otherwise, in accordance with applicable law.

Furthermore, odd lot holders who hold shares registered in their names and
tender their shares directly to the Depositary and Paying Agent and whose shares are purchased pursuant to the Offer will avoid any applicable odd lot discounts that might be payable on sales of their shares. See Section 1.

Yes. The completion of the Offer in accordance with its terms and conditions will not cause the Company to stop being quoted on the NYSE or to
stop being subject to the periodic reporting requirements of the Securities Exchange Act of 1934, as amended (the Exchange Act).

The consummation of the Offer will decrease the Companys public float (the number of shares owned by non-affiliate
shareholders and available for trading in the securities markets), which may result in less liquidity and trading volume of the shares and could potentially result in an increase in price volatility. Shareholders may not be able to sell non-tendered
shares in the future on NYSE or otherwise at a net price higher than the value of the Cash Purchase Price in the Offer. We can give no assurance as to the price at which a shareholder may be able to sell his or her shares in the future.

What are the significant conditions to the Offer?

Our obligations to accept and pay for your tendered shares depends upon a number of conditions that must be satisfied or waived by us prior to
the Expiration Time, including, but not limited to:



The reported market price of the common shares at the close of trading on the Expiration Time shall not be greater than $113.40 (which amount is 5% greater than the highest Cash Purchase Price possible under the Offer)
or less than $93.10 (which amount is 5% less than the lowest Cash Purchase Price possible under the Offer).



No legal action shall have been instituted, threatened, or been pending that challenges the Offer or seeks to impose limitations on our ability (or any affiliate of ours) to acquire or hold or to exercise full rights of
ownership of the shares.



No material adverse change in the business, condition (financial or otherwise), assets, income, operations, prospects or stock ownership of the Company shall have occurred.



No one shall have proposed, announced or made a tender or exchange offer (other than this Offer), merger, business combination or other similar transaction involving the Company or any subsidiary of the Company.



No one shall have filed a Notification and Report Form under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, or made a public announcement reflecting an intent to acquire the Company or any of its
subsidiaries.



No commencement or escalation of war, armed hostilities, terrorism or other similar national or international calamity, directly or indirectly involving the United States, shall have occurred.



No general suspension of, or general limitation on prices for, or trading in, securities on any national securities exchange in the United States or in the over-the-counter market shall have occurred.



Any approval, permit, authorization, favorable review or consent of any governmental entity required to be obtained in connection with the Offer has not been obtained on terms satisfactory to us in our reasonable
discretion.

The Offer is subject to a number of other conditions described in greater detail in Section 7. Each of
these conditions is for our sole benefit and may be asserted or waived by us, in whole or in part, at any time and from time to time in our discretion prior to the Expiration Time.

How do I tender my shares?

If you want
to tender all or part of your shares, you must do one of the following before the Expiration Time:



If your shares are registered in the name of a broker, dealer, commercial bank, trust company or other nominee, you must contact the nominee and request that the nominee tender your shares for you.

If you hold certificates in your own name, you must complete and sign a Letter of Transmittal according to its instructions, and deliver it, together with any required signature guarantees, the certificates for your
shares and any other documents required by the Letter of Transmittal, to the Depositary and Paying Agent.



If you are an institution participating in the book-entry transfer facility (as defined herein), you must tender your shares according to the procedure for book-entry transfer described in Section 3.

You may contact the Information Agent for assistance. The contact information for the Information Agent appears on the back
cover of this Offer to Purchase. See Section 3 and the Instructions to the Letter of Transmittal.

If you are a participant in the
Companys Employee Stock Purchase Plan (ESPP), you may tender shares that you have purchased through the ESPP. If you have purchased shares through the ESPP and hold such shares at Computershare Plan Managers, the administrator of
our ESPP (the Plan Admin), contact the Plan Admin and request that the Plan Admin tender your shares. You must follow the procedures described in the separate instructions that you will receive and accept the Offer by 5:00 P.M., New York
City Time, on Friday, May 11, 2018, unless the offer is extended. See Section 3.

Shareholders who hold shares through the
Companys ESPP should be aware that they have an earlier deadline for participation in the Offer. Accordingly, such shareholders should refer to the separate instructions that they have received or contact the Plan Admin as soon as possible for
details with respect to the deadline such shareholder must take action in order to participate in the Offer. See Section 3.

What happens if the
Companys purchase of all shares tendered in the Offer would result in an aggregate Cash Purchase Price of more than $600 million?

If our purchase of all shares properly tendered at or below the Cash Purchase Price and not properly withdrawn prior to the Expiration Time in
the Offer would result in an aggregate Cash Purchase Price of more than $600 million, we will purchase shares:



first, from all holders of odd lots of less than 100 shares at the Expiration Time who properly tender all of their shares at or below the Cash Purchase Price;



second, from all other shareholders that properly tender shares at or below the Cash Purchase Price, on a pro rata basis (except for shareholders that tendered shares conditionally for which the condition was not
satisfied); and



third, only if necessary to permit us to purchase shares for an aggregate Cash Purchase Price of up to $600 million, from holders who have properly tendered shares at or below the Cash Purchase Price
conditionally (for which the condition was not initially satisfied), by random lot, to the extent feasible. To be eligible for purchase by random lot, shareholders whose shares are conditionally tendered must have properly tendered all of their
shares.

Because of the odd lot priority, proration and conditional tender provisions described above, we may
not purchase all of the shares that you properly tender even if you tender them at or below the Cash Purchase Price. See Section 1.

If I own
fewer than 100 shares at the Expiration Time and I tender all of my shares, will I be subject to proration?

If you own beneficially or
of record fewer than 100 shares in the aggregate at the Expiration Time, you properly tender all of these shares at or below the Cash Purchase Price and you complete the section entitled Odd Lots in the Letter of Transmittal, we will
purchase all of your shares without subjecting them to the proration procedure, unless the aggregate amount of Odd Lot tenders at or below the Cash Purchase Price exceeds an aggregate Cash Purchase Price of $600 million. See
Section 1.

Yes. You may withdraw any shares you have tendered at any time before 5:00 p.m., New York City time, on May 16, 2018, unless we extend the
Offer, in which case you can withdraw your shares until the expiration of the Offer as extended. If we have not accepted for payment the shares you have tendered to us, you may also withdraw your shares at any time after 12:00 midnight, New York
City time, on June 14, 2018. See Section 4.

How do I properly withdraw shares I previously tendered?

To properly withdraw shares, you must deliver a written notice of withdrawal with the required information to the Depositary and Paying Agent
while you still have the right to withdraw the shares. Your notice of withdrawal must specify your name, the number of shares to be withdrawn and the name of the registered holder of these shares. Some additional requirements apply if the share
certificates to be withdrawn have been delivered to the Depositary and Paying Agent or if your shares have been tendered under the procedure for book-entry transfer set forth in Section 3. See Section 4. If you have tendered your shares by
giving instructions to a broker, dealer, commercial bank, trust company or other nominee, you must instruct the nominee to arrange for the withdrawal of your shares.

Do the terms of the Offer take into account the Companys previously announced stock split?

Yes. All Offer terms, including the Cash Purchase Price, described herein are based on the pre-stock split number of common shares
outstanding, as well as on the prevailing trading price for the common shares in the market before completion of the stock split. Following the stock split, the Cash Purchase Price will be adjusted ratably to account for the increased number of
common shares outstanding on a post-split basis. See Section 8.

Do I need to be a record holder of common shares on the stock split record date
in order to tender my common shares in the Offer?

No, all shareholders who own shares can tender their common shares regardless of
whether they held common shares on the stock split record date (May 7, 2018) or the stock split distribution date (May 14, 2018). Eligibility to tender is not conditioned on being a shareholder of record on the stock split record date or
stock split distribution date.

When are the common shares expected to split under the Companys previously announced two-for-one stock split?

The previously announced record date for the proposed stock split is May 7, 2018. If the stock split is approved by
shareholders at the Companys Annual General Meeting of Shareholders on April 24, 2018, the Company expects to distribute the additional common shares in connection with the stock split on or about May 14, 2018, the stock split
distribution date, and the common shares are expected to go ex-dividend the following day on May 15, 2018, the stock split ex-dividend date. The Offer is currently scheduled to expire after both the stock split distribution date and the
stock split ex-dividend date. Following the stock split, the Cash Purchase Price will be adjusted ratably to account for the increased number of common shares outstanding on a post-split basis. See Section 8.

In light of the anticipated stock split, how should I complete the tender offer documentation if I want to tender common shares in the Offer?

Shareholders that wish to tender common shares in the Offer should complete the Letter of Transmittal (and any other documents used to tender
common shares) specifying the number of common shares, and the cash purchase price(s) per share, that they are tendering on a pre-stock split basis. Following the stock split, the Cash Purchase Price will be adjusted ratably to account for the
increased number of common shares outstanding on a post-split basis. See Section 8 and Instruction 5 of the Letter of Transmittal.

The Board has unanimously approved the Offer. However, none of Board, the Company, the Depositary and Paying Agent or the Information Agent is
making any recommendation to you as to whether you should tender or refrain from tendering your shares or as to the purchase price or purchase prices at which you may choose to tender your shares. You must make your own decision as to whether to
tender your shares and, if so, how many shares to tender and the purchase price or purchase prices at which your shares should be tendered. In so doing, you should read carefully the information in this Offer to Purchase and in the related Letter of
Transmittal, including our reasons for making the Offer.

Do the directors or executive officers of the Company intend to tender their shares in the
Offer?

None of the directors or executive officers of the Company intend to tender any of their shares in the Offer. See
Section 11.

If I decide not to tender, how will the Offer affect my shares?

Shareholders that choose not to tender their shares will own a greater percentage interest in the outstanding common shares following the
consummation of the Offer. See Section 2.

When will the Company pay for the shares I tender?

We will pay the Cash Purchase Price, net to the seller in cash, less any applicable tax withholding and without interest, and as adjusted for
any stock split, for the shares we accept for purchase promptly after the Expiration Time. We do not expect, however, to announce the results of proration and begin paying for tendered shares until up to ten business days after the Expiration Time.
See Section 5.

Will I have to pay brokerage commissions if I tender my shares?

If you are the record owner of your shares and you tender your shares directly to the Depositary and Paying Agent, you will not have to pay
brokerage fees or similar expenses. If you own your shares through a broker, dealer, commercial bank, trust company or other nominee and the nominee tenders your shares on your behalf, the nominee may charge you a fee for doing so. You should
consult with your broker, dealer, commercial bank, trust company or other nominee to determine whether any charges will apply. See Section 3.

What are the U.S. federal income tax consequences if I tender my shares?

Generally, if you are a U.S. Holder (as defined in Section 14), the receipt of the Cash Purchase Price for your shares pursuant to the
Offer will be a taxable transaction for U.S. federal income tax purposes. The specific U.S. federal income tax consequences of the transaction will depend in part on whether the transaction is treated as sale or exchange of shares or a distribution
in respect of your shares for U.S. federal income tax purposes. You should consult your tax advisor regarding the tax consequences to you of participating in the Offer in light of your circumstances. See Sections 3 and 14 for a more detailed
discussion of certain material U.S. federal income tax consequences of the Offer.

All shareholders should review the discussion in
Sections 3 and 14 regarding tax issues and consult their tax advisor with respect to the tax consequences of a tender of shares in their particular circumstances.

Will I have to pay stock transfer tax if I tender my shares?

We will pay all stock transfer taxes unless payment is made to, or if shares not tendered or accepted for payment are to be registered in the
name of, someone other than the registered holder, or tendered certificates are registered in the name of someone other than the person signing the Letter of Transmittal. See Section 5.

Does the Company intend to repurchase any shares other than pursuant to the Offer during or after the
Offer?

Rule 13e-4(f) under the Exchange Act prohibits the Company and its affiliates from purchasing any shares, other than in the
Offer, until at least 10 business days after the Expiration Time. Accordingly, any repurchases outside of the Offer may not be consummated until at least 10 business days after the Expiration Time. See Section 10.

None of the directors or executive officers of the Company intend to tender any of their shares in the Offer. See Section 11. In
addition, the directors and executive officers of the Company and the Icahn Entities (as defined below) are prohibited from purchasing or otherwise acquiring any common shares until the expiration of ten business days after the date of termination
of the Offer, as required by Rules 13e-4(f)(6) and 14e-5 under the Exchange Act.

Additionally, in connection with the Companys
prior tender offer in 2017 (the Prior Offer), the Company entered into an agreement with the Mr. Carl C. Icahn and all of his controlled affiliates holding shares (together, the Icahn Entities) on August 21,
2017, which is annexed to and filed with the corresponding Schedule TO as Exhibit (d)(1) (the Icahn Letter Agreement). Pursuant to the Icahn Letter Agreement, the Icahn Entities agreed, among other things, that until August 21, 2019
(two years following commencement of the Prior Offer), the Icahn Entities will not purchase or otherwise acquire common shares that would increase their aggregate beneficial ownership above 50% of the outstanding common shares unless they have
agreed to acquire 100% of the outstanding common shares. Notwithstanding the foregoing, for the purposes of the Icahn Letter Agreement, the Icahn Entities will be deemed not to have increased their aggregate beneficial ownership above 50% of the
outstanding common shares if the increase in their aggregate beneficial ownership percentage occurs as a result of a reduction in the outstanding common shares. Thus, any future repurchase of shares by the Company, either as part of the Offer,
Herbalifes current share repurchase program described below or otherwise, could have the potential effect of increasing the Icahn Entities beneficial ownership above 50% of the outstanding common shares without the Icahn Entities being
required to acquire 100% of the outstanding common shares pursuant to the Icahn Letter Agreement.

How many shares has the Board authorized to be
repurchased and how many shares have been repurchased thus far?

On February 21, 2017, our Board authorized a new three-year $1.5
billion share repurchase program that will expire on February 21, 2020, which replaced our prior share repurchase authorization that was set to expire on June 30, 2017. As of April 16, 2018, our current share repurchase program had
approximately $713.3 million of remaining authorized capacity. This share repurchase program allows the Company, including an indirect, wholly-owned subsidiary to repurchase shares, at such times and prices as
determined by the Companys management as market conditions warrant and to the extent our distributable reserves are available under Cayman Islands law. The Credit Facility permits us to repurchase shares as long as no default or event of
default exists and other conditions, such as specified consolidated leverage ratios, are met.

In October 2017, the Company completed the
Prior Offer and subsequently paid cash to repurchase approximately 6.7 million of its common shares at an aggregate cost of approximately $457.8 million, or $68.00 per share. In addition, as of April 16, 2018, an indirect,
wholly-owned subsidiary of the Company (HBL Swiss) has repurchased approximately 5.0 million common shares through open market purchases at an aggregate cost of approximately $328.9 million, or an average cost of approximately
$65.62 per share. Although these shares are owned by HBL Swiss, they are reflected as treasury shares under U.S. GAAP and therefore reduce the number of common shares outstanding within our condensed consolidated financial statements and the
weighted-average number of common shares outstanding used in calculating our earnings per share. The Companys shares held by HBL Swiss, however, remain outstanding on the books and records of the Companys transfer agent and therefore
still carry voting and other share rights related to ownership of the Companys

common shares. Following the Prior Offer, on October 25, 2017, HBL Swiss filed a Schedule 13G disclosing its aggregate beneficial ownership and noting the common shares held by HBL Swiss
will be voted in the same manner, and to the maximum extent possible, in the same proportion, as all other votes cast with respect to any matter properly submitted to a vote of the Companys shareholders, so long as it is consistent with
applicable laws.

The shares purchased by the Company in this Offer will be purchased as a part of the Companys ongoing share
repurchase program.

Is the Company offering any guaranteed delivery procedures in connection with the Offer?

No, the Company is not offering any guaranteed delivery procedures to shareholders seeking to tender common shares in the Offer.

performance or events.

Forward-looking statements may include the words may, will, estimate,
intend, continue, believe, expect or anticipate and any other similar words. Although we believe that the expectations reflected in any of our forward-looking statements are reasonable,

February 22, 2018, as well as the risks and uncertainties discussed in the Companys other filings with the SEC, including risks resulting from a decrease in the public float of the shares which may result in less liquidity and trading
volume of the shares after the consummation of the Offer and could result in an increase in price volatility. We qualify all of our forward-looking statements by these cautionary statements. We caution you that these risks are not exhaustive. We
operate in a continually changing business environment and new risks emerge from time to time.

We invite the shareholders of the Company to tender their common shares of the Company. Upon the terms and subject to the conditions of this
Offer to Purchase and the related Letter of Transmittal, the Company is offering to purchase common shares for an aggregate Cash Purchase Price of up to $600 million and at a per share price of not greater than $108.00 nor less than $98.00, net to
the seller in cash, less applicable tax withholding and without interest, and as adjusted for any stock split. Upon the terms and subject to the conditions of the Offer, the Company will purchase common shares properly tendered and not properly
withdrawn in the Offer for an aggregate Cash Purchase Price of up to $600 million.

The Offer will expire at 5:00 p.m., New York City
time, on May 16, 2018, unless extended.

Upon the terms and subject to the conditions of the Offer, promptly after the Expiration
Time we will determine a single per share price, which will be not greater than $108.00 nor less than $98.00 per share, net to the seller in cash (the Cash Purchase Price), less any applicable tax withholding and without interest, and as
adjusted for any stock split, that we will pay for shares properly tendered, for an aggregate Cash Purchase Price of up to $600 million. The Cash Purchase Price will be the lowest price per share of not greater than $108.00 nor less than $98.00 per
share (in multiples of $0.25), as adjusted for any stock split, at which shares have been properly tendered that will enable us to purchase the maximum number of shares for an aggregate Cash Purchase Price of up to $600 million. If fewer than such
number of shares as would enable us to purchase shares pursuant to the Offer for an aggregate Cash Purchase Price of up to $600 million are properly tendered, we will select the lowest price that will allow us to buy all the shares that are properly
tendered.

All shares we purchase in the Offer will be purchased at the same Cash Purchase Price regardless of whether the shareholder
tendered, or is deemed to have tendered, at a lower cash price. We will not purchase any shares from shareholders that do not properly tender any of their common shares pursuant to the Offer prior to the Expiration Time.

If our purchase of all shares properly tendered at or below the Cash Purchase Price and not properly withdrawn in the Offer would result in an
aggregate Cash Purchase Price of more than $600 million, we will purchase all shares properly tendered at or below the Cash Purchase Price on a pro rata basis, except for odd lots (lots held by owners of less than 100 shares at the
Expiration Time), which we will purchase on a priority basis, and except for each conditional tender whose condition was not met, which we will not purchase. Tendering shareholders will receive a cash payment only if their tendered shares are
purchased. Shares tendered but not purchased pursuant to the Offer will be returned to the tendering shareholders at our expense promptly following the Expiration Time. See Section 1.

Tendering shareholders whose shares are registered in their own names and who tender directly to the Depositary and Paying Agent will not be
obligated to pay brokerage fees or commissions or, except as set forth in Instruction 7 to the Letter of Transmittal, stock transfer taxes on the purchase of shares by us under the Offer. If you own your shares through a broker, dealer, commercial
bank, trust company or other nominee and the nominee tenders your shares on your behalf, the nominee may charge you a fee for doing so. You should consult your broker, dealer, commercial bank, trust company or other nominee to determine whether any
charges will apply.

The number of common shares subject to the Offer and the price per share relate to the common shares as outstanding
on the date of the Offer. The Expiration Time is currently scheduled two days after the stock split distribution date (May 14, 2018), when the Company expects to effect a two-for-one stock split as described in the Companys 2018 proxy
statement. Following the stock split, the Cash Purchase Price will be adjusted ratably to account for the increased number of common shares outstanding on a post-split basis. See Section 8.

Our obligation to accept, and pay for, shares properly tendered pursuant to the Offer is
conditioned upon satisfaction or waiver of the conditions set forth in Section 7 of this Offer to Purchase.

Section 14
describes certain material United States federal income tax consequences to a U.S. Holder (as defined in Section 14) of an exchange of shares pursuant to the Offer.

We will pay the fees and expenses incurred in connection with the Offer by the Depositary and Paying Agent and the Information Agent for this
Offer. See Section 17.

The Board has unanimously approved the Offer pursuant to the recommendation of the Committee. However,
none of the Board, the Committee, the Company, the Depositary and Paying Agent, or the Information Agent is making any recommendation to you as to whether to tender or refrain from tendering your shares or as to the purchase price or purchase prices
at which you may choose to tender your shares. You must make your own decision as to whether to tender your shares and, if so, how many shares to tender and the price or prices at which you will tender them. In doing so, you should read carefully
the information in this Offer to Purchase and in the related Letter of Transmittal, including our reasons for making the Offer. See Section 2.

As of April 16, 2018, there were 88,202,525 common shares outstanding. The shares are quoted on the NYSE under the symbol
HLF. On April 17, 2018, the last full trading day before we commenced the Offer, the closing price of the shares as quoted on NYSE was $103.02 per share, which is greater than the low end of the price range for the Offer of
$98.00 per share. Shareholders are urged to obtain current market quotations for the shares before deciding whether and at what purchase price or purchase prices to tender their shares. See Section 8.

General. Upon the terms and subject to the conditions of this Offer, the Company is offering to purchase common shares for an aggregate
Cash Purchase Price of up to $600 million and at a per share price of not greater than $108.00 nor less than $98.00, net to the seller in cash, less applicable tax withholding and without interest, and as adjusted for any stock split, upon the terms
and subject to the conditions described in this Offer. Upon the terms and subject to the conditions of the Offer, the Company will purchase common shares properly tendered and not properly withdrawn for an aggregate Cash Purchase Price of $600
million.

The number of common shares subject to the Offer and the price per share relate to the common shares as outstanding on the date
of the Offer. The Expiration Time is currently scheduled two days after the stock split distribution date (May 14, 2018), when the Company expects to effect a two-for-one stock split as described in the Companys 2018 proxy statement. Following
the stock split, the Cash Purchase Price will be adjusted ratably to account for the increased number of common shares outstanding on a post-split basis. See Section 8.

The term Expiration Time means 5:00 p.m., New York City time, on May 16, 2018. We may, in our sole discretion, choose to
extend the period of time during which the Offer will remain open, subject to applicable laws. In the event of an extension of the Offer, the term Expiration Time shall refer to the latest time and date at which the Offer, as so extended
by us, shall expire. See Section 15 for a description of our right to extend, delay, terminate or amend the Offer.

The proration
period and, except as described herein, withdrawal rights, will expire at the Expiration Time.

The Offer is subject to certain
conditions. See Section 7.

We are conducting the Offer through a procedure commonly called a modified Dutch Auction.
This procedure allows shareholders to select the price (in multiples of $0.25) within a price range specified by us at which they are willing to sell their shares. The price range for the Offer is $98.00 to $108.00 per share. If you would like to
tender your shares, you must specify the price or prices, not in excess of $108.00 nor less than $98.00 (in multiples of $0.25) per share, at which you are willing to sell your shares to us under the Offer. Alternatively, if you would like to tender
your shares, you may choose not to specify a price and, instead, elect to tender your shares at the Cash Purchase Price (as defined herein) ultimately paid for shares properly tendered in the Offer. If you agree to accept the Cash Purchase Price,
your shares will be deemed to be tendered at the minimum cash price of $98.00 per share. See Section 8 for recent market prices for the shares.

Upon the terms and subject to the conditions of the Offer, promptly following the Expiration Time, we will determine a single per share price,
which will be not greater than $108.00 nor less than $98.00 per share, net to the seller in cash (the Cash Purchase Price), less any applicable tax withholding and without interest, and as adjusted for any stock split, that we will pay
for shares properly tendered, for an aggregate Cash Purchase Price of up to $600 million. Once the Cash Purchase Price has been determined, we intend to promptly disclose such price in a manner calculated to inform shareholders of this information,
which will include a press release.

The Cash Purchase Price will be the lowest price per share of not greater than $108.00 nor less than
$98.00 per share (in multiples of $0.25), as adjusted for any stock split, at which shares have been properly tendered in the Offer, that will enable us to purchase the maximum number of shares for an aggregate Cash Purchase Price of up to $600
million. If fewer than such number of shares as would enable us to purchase shares pursuant to the Offer for an aggregate Cash Purchase Price of up to $600 million are properly tendered, we will select the lowest price that will allow us to buy all
the shares that are properly tendered.

As previously announced, the Board has approved, and is currently soliciting shareholder approval
of a two-for-one stock split of the common shares. If the stock split is approved by the affirmative vote of a majority of

common shares present or represented by proxy and entitled to vote on such stock split proposal on April 24, 2018 at the Companys Annual General Meeting of Shareholders, then on
May 7, 2018 (the stock split record date) each issued and outstanding common share, par value US $0.001 per share, would be subdivided into two common shares, par value US $0.0005 per share, and the Companys currently
authorized share capital of 1,000,000,000 common shares, par value US $0.001 per share, would be subdivided into 2,000,000,000 common shares, par value US $0.0005 per share (the stock split). Assuming the stock split is approved by
shareholders on April 24, 2018, the Company expects to distribute the additional common shares in connection with the stock split on or about May 14, 2018 (the stock split distribution date) and expects the common shares will
go ex-dividend the following day on May 15, 2018 (the stock split ex-dividend date).

The stock split distribution date is currently scheduled two days prior to the Expiration Time. All Offer terms, including the Cash Purchase
Price, described herein are based on the pre-stock split number of common shares outstanding, as well as on the prevailing trading price for the common shares in the market before the completion of the stock split. Following the stock split, the
Cash Purchase Price will be adjusted ratably to account for the increased number of common shares outstanding on a post-split basis. See Section 8.

Shareholders should complete the Letter of Transmittal (and any other documents used to tender common shares) specifying the number of
common shares, and the cash purchase price(s) per share, they are tendering in the Offer on a pre-stock split basis.

If our purchase of all shares properly tendered at or below the Cash Purchase Price and not properly withdrawn in the Offer would result in an
aggregate Cash Purchase Price of more than $600 million, we will purchase all shares properly tendered at or below the Cash Purchase Price on a pro rata basis, except for odd lots (lots held by owners of less than 100 shares at the
Expiration Time), which we will purchase on a priority basis, and except for each conditional tender whose condition was not met, which we will not purchase. All shares we acquire in the Offer will be acquired at the same Cash Purchase Price
regardless of whether you tendered your shares, or are deemed to have tendered your shares, at a lower cash price. We will not purchase any shares from shareholders that do not properly tender any of their common shares pursuant to the Offer prior
to the Expiration Time. Tendering shareholders will receive a cash payment only if their tendered shares are purchased. Shares tendered but not purchased pursuant to the Offer will be returned to the tendering shareholders at our expense promptly
after the Offer expires.

We expressly reserve the right, in our sole discretion, to change the per share purchase price range and to
increase or decrease the value of shares sought in the Offer. We may increase the value of shares sought in the Offer to an amount greater than $600 million, subject to applicable law. In accordance with the rules of the SEC, we may increase the
value of shares sought in the Offer and thereby increase the number of shares purchasable in the Offer by no more than 2% of the outstanding shares without amending or extending the Offer. However, if we purchase an additional number of shares in
excess of 2% of the outstanding shares, we will amend and extend the Offer in compliance with applicable law. See Section 15.

You
may specify one cash price for a specified portion of your shares and a different cash price for other specified shares, but you must submit a separate Letter of Transmittal for shares tendered at each cash price. See Instruction 5 to the Letter of
Transmittal.

You may also specify the order in which we will purchase the specified portions of your shares in the event that, as a
result of the proration provisions or otherwise, we purchase some but not all of the tendered shares pursuant to the Offer. In the event you do not designate the order in which we should purchase specified portions of your shares, and fewer than all
shares are purchased due to proration, the Depositary and Paying Agent will select the order of shares purchased.

Priority of
Purchases. Upon the terms and subject to the conditions of the Offer, if our purchase of all shares properly tendered at or below the Cash Purchase Price and not properly withdrawn prior to the Expiration Time

in the Offer would result in an aggregate Cash Purchase Price of more than $600 million, we will purchase properly tendered shares on the basis set forth below:



First, upon the terms and subject to the conditions of the Offer, we will purchase all shares properly tendered and not properly withdrawn by any Odd Lot Holder (as defined herein) who:



properly tenders and does not properly withdraw all shares owned beneficially of record by the Odd Lot Holder at a price at or below the Cash Purchase Price (tenders of less than all of the shares owned by the Odd Lot
Holder will not qualify for this preference); and



completes the section entitled Odd Lots in the Letter of Transmittal.



Second, subject to the conditional tender provisions described in Section 6, we will purchase all other shares properly tendered at prices at or below the Cash Purchase Price on a pro rata basis with
appropriate adjustments to avoid purchases of fractional shares, as described below.



Third, if necessary to permit us to purchase shares for an aggregate Cash Purchase Price of up to $600 million, shares conditionally tendered (for which the condition was not initially satisfied) at or below
the Cash Purchase Price, will, to the extent feasible, be selected for purchase by random lot. To be eligible for purchase by random lot, shareholders whose shares are conditionally tendered must have properly tendered all of their shares.

As a result of the foregoing priorities applicable to the purchase of shares tendered, it is possible that all of the
shares that a shareholder properly tenders in the Offer may not be purchased even if they are tendered at prices at or below the Cash Purchase Price. In addition, if a tender is conditioned upon the purchase of a specified number of shares, it is
possible that none of those shares will be purchased even though those shares were tendered at prices at or below the Cash Purchase Price.

Odd Lots. The term odd lots means all shares properly tendered prior to the Expiration Time at prices at or below the Cash
Purchase Price by any person (an Odd Lot Holder) who owned beneficially or of record a total of fewer than 100 shares at the Expiration Time and so certified in the appropriate place on the Letter of Transmittal.

To qualify for this preference, an Odd Lot Holder must properly tender all shares owned by the Odd Lot Holder in accordance with the
procedures described in Section 3. Odd Lots will be accepted for payment before any proration of the purchase of other tendered shares. This preference is not available to partial tenders or to beneficial or record holders of an aggregate of
100 or more shares, even if these holders have separate accounts or certificates representing fewer than 100 shares at the Expiration Time. By tendering in the Offer, an Odd Lot Holder who holds shares in its name and tenders its shares directly to
the Depositary and Paying Agent would not only avoid the payment of brokerage commissions, but also would avoid any applicable odd lot discounts in a sale of the holders shares. Any Odd Lot Holder wishing to tender all of its shares pursuant
to the Offer should complete the section entitled Odd Lots in the Letter of Transmittal. As described in Section 8, the Company has proposed and is currently soliciting shareholder approval of a two-for-one stock split of the common
shares. If approved by shareholders, the stock split is expected to become effective before the Expiration Time. Accordingly, some holders of fewer than 100 shares (before the stock split) may own beneficially or of record an aggregate of 100 or
more shares (following the stock split) and thus would not qualify for this preference.

Proration. If proration of properly
tendered shares is required, we will determine the proration factor promptly following the Expiration Time. Subject to adjustment to avoid the purchase of fractional shares and subject to the provisions governing conditional tenders described in
Section 6, proration for each shareholder tendering shares, other than Odd Lot Holders, will be based on the ratio of the number of shares properly tendered by the shareholder to the total number of shares properly tendered by all shareholders,
other than Odd Lot Holders, at or below the Cash Purchase Price. Because of the difficulty in determining the number of shares properly tendered and not properly withdrawn, and because of the odd lot procedure described above and the

conditional tender procedure described in Section 6, we expect that we will not be able to announce the final proration factor or commence payment for any shares purchased pursuant to the
Offer until up to ten business days after the Expiration Time. The preliminary results of any proration will be announced by press release promptly after the Expiration Time. After the Expiration Time, shareholders may obtain preliminary proration
information from the Information Agent and also may be able to obtain the information from their brokers.

As described in
Section 14, the number of shares that we will purchase from a shareholder under the Offer may affect the U.S. federal income tax consequences to that shareholder and, therefore, may be relevant to a shareholders decision whether or not to
tender shares and whether to condition any tender upon our purchase of a stated number of shares held by such shareholder.

This Offer to
Purchase and the related Letter of Transmittal will be mailed to record holders of shares and will be furnished to brokers, dealers, commercial banks and trust companies whose names, or the names of whose nominees, appear on the Companys
shareholder list or, if applicable, who are listed as participants in a clearing agencys security position listing for subsequent transmittal to beneficial owners of shares.

2. Purpose of the Tender Offer; Certain Effects of the Tender Offer; Other Plans

Purpose of the Tender Offer.

We believe that the repurchase of shares pursuant to the Offer is consistent with our long-term goal of maximizing shareholder value. On
April 12, 2018, the Board unanimously approved this Offer pursuant to the recommendation of the Committee. In determining to proceed with the Offer, the Board evaluated the Companys operations, financial condition, capital needs,
regulatory requirements, strategy and expectations for the future and believes that the Offer is a prudent use of the Companys financial resources. The Board determined that a tender offer is an appropriate mechanism to return capital to
shareholders that seek liquidity under current market conditions and to allow shareholders that do not participate in the Offer to share in a higher portion of the Companys future potential. The Board believes that the Offer provides a
mechanism to give the Companys shareholders the opportunity to tender all or a portion of their shares and, thereby, receive a return of capital if they so elect. In addition, shareholders that do not participate in the Offer will
automatically increase their relative percentage interest in the Company and its future operations at no additional cost to them if the Offer is consummated. As a result, the Board believes that investing in the Companys own shares at this
time and in this manner is an attractive use of capital and an efficient means to provide value to the Companys shareholders.

The
shares to be purchased by the Company in this Offer will be purchased pursuant to the aggregate authorization of the Companys share repurchase program authorized by the Board on February 21, 2017. The Offer will allow the Company to
repurchase a large number of shares at one time. As of April 16, 2018, the Company held approximately 5.0 million of treasury shares for GAAP purposes as a result of the share repurchase program. The remaining authorized capacity under the
Companys $1.5 billion share repurchase program as of April 16, 2018 was approximately $713.3 million. The maximum aggregate Cash Purchase Price the Company would spend to purchase shares properly tendered in the Offer is $600 million. See
Section 8.

If you properly tender all of your shares pursuant to the Offer, and your shares are purchased in the Offer by the
Company, you will cease to have any interest in the Company and will not have the opportunity to participate in the future earnings or growth, if any, of the Company or bear the burden and risks of any decrease in value of the Company.

We believe that buying shares in the Offer represents an attractive use of capital. We also believe that the modified Dutch
Auction tender offer set forth in this Offer to Purchase represents a mechanism to provide all of the shareholders of the Company with the opportunity to tender all or a portion of their shares and, thereby, receive a return of their
investment if they so elect. The Offer provides such shareholders (particularly those who,

because of the size of their shareholdings, might not be able to sell their shares without potential disruption to the share price) with an opportunity to obtain liquidity with respect to all or
a portion of their shares, without potential disruption to the share price or incurring brokers fees, commissions or other usual transaction costs associated with open market sales.

Furthermore, odd lot holders who hold shares registered in their names and tender their shares directly to the Depositary and Paying Agent and
whose shares are purchased pursuant to the Offer will avoid any applicable odd lot discounts that might be payable on sales of their shares. See Section 1.

The Board has unanimously approved the Offer pursuant to the recommendation of the Committee. However, none of the Board, the Committee,
the Company, the Depositary and Paying Agent or the Information Agent is making any recommendation to any shareholder as to whether to tender or refrain from tendering any shares or as to the purchase price or purchase prices at which shareholders
may choose to tender their shares. We have not authorized any person to make any such recommendation. Shareholders should carefully evaluate all information in the Offer. Shareholders are also urged to consult with their tax advisors to determine
the consequences to them of participating or not participating in the Offer, and should make their own decisions about whether to tender shares and, if so, how many shares to tender and the cash purchase price or cash purchase prices at which to
tender. In doing so, shareholders should read carefully the information in this Offer to Purchase and in the related Letter of Transmittal.

Certain Effects of the Offer. Shareholders that do not tender their shares pursuant to the Offer and shareholders that otherwise retain
an equity interest in the Company as a result of a partial tender of shares or proration will continue to be owners of the Company. As a result, those shareholders will realize a proportionate increase in their relative equity interest in the
Company and, thus, in the Companys future earnings and assets, if any, and will bear the attendant risks associated with owning the Companys equity securities. These risks include risks resulting from a decrease in the public float of
the shares which may result in less liquidity and trading volume of the shares after the consummation of the Offer and could potentially result in an increase in price volatility. Shareholders may not be able to sell non-tendered shares in the
future on the NYSE or otherwise at a net price higher than the Cash Purchase Price in the Offer. We can give no assurance as to the price at which a shareholder may be able to sell his, her, or its shares in the future.

Shares that the Company purchases pursuant to the Offer will be cancelled. There can be no assurance that the Company will issue additional
shares or equity interests in the future. Please note that the foregoing description of the treatment of shares following their repurchase differs from the treatment of the shares repurchased and held by one of the Companys indirect,
wholly-owned subsidiaries, which shares have not been cancelled. See Section 8Share Repurchases.

The Offer will reduce the
Companys public float and is likely to reduce the number of the Companys shareholders. These reductions may result in lower share prices and less liquidity in the trading market for the Companys common shares following completion
of the Offer.

The anti-dilution adjustment provisions of the Companys existing outstanding 2% convertible notes due 2019 and 2.625%
convertible notes due 2024 may require an increase in the conversion rate applicable to the convertible notes based on a formula in which the aggregate consideration paid in the tender offer plus the aggregate value of the outstanding common shares
immediately following the tender offer is divided by the aggregate value of the outstanding common shares prior to the tender offer, with each such aggregate value to be determined based on the price of the common shares after the Expiration Time.
However, the value of several of the variables needed to calculate this formula will not be known until the Expiration Time.

The
variables in the formula consist of (i) the number of common shares outstanding immediately after the Expiration Time (the determination of which depends on how many shareholders tender their common shares in the Offer), (ii) the
number of common shares outstanding immediately prior to the Expiration Time (which

number may fluctuate between the launch of the Offer and the Expiration Time) and (iii) the average of the last reported sale prices of the common shares over the 10 consecutive trading date
period commencing on, and including, the trading day following the day on which the Expiration Time occurs. See Section 4.04(e) of the indenture for the 2% convertible notes due 2019 and Section 4.04(e) of the indenture for the
2.625% convertible notes due 2024. No adjustment will be made, however, if it would result in the conversion rate being decreased. In addition, the Company may defer any increase of less than 1% in the conversion rate as described in the indentures
for the convertible notes. The indentures will require the Company to take any such carried forward adjustment into account in the adjustment which is anticipated to occur in connection with the proposed stock split of the Companys common
shares.

The strike price of the Companys capped call transactions that were entered into with respect to the convertible notes due
2019 will be reduced to track any increase in the conversion rate of the convertible notes as described above, and the cap price thereunder will be reduced accordingly. In addition, the counterparties to the capped call transactions may have the
right to further reduce the cap price, in their commercially reasonable discretion, if they determine that the repurchase has a material effect on the theoretical value of the shares or options on the shares, to account for that effect.

Under the forward share repurchase transactions the Company entered into in connection with the 2% convertible notes, the counterparties to
such transaction may have the right to adjust the terms thereunder (which adjustment we would expect to take the form of a reduction to the number of shares that the counterparties are required to deliver on maturity of the contracts), in their
commercially reasonable discretion, if they determine that the repurchase pursuant to the Offer has a dilutive or concentrative effect on the theoretical value of the shares, to reflect that dilutive or concentrative effect.

3. Procedures for Tendering Shares

Proper Tender. For a shareholder to make a proper tender of shares under the Offer, the Depositary and Paying Agent must receive at one
of its addresses set forth on the back cover of this Offer to Purchase and prior to the Expiration Time:



a Letter of Transmittal, properly completed and duly executed, together with any required signature guarantees, or, in the case of a book-entry transfer, an agents message (see Book-Entry
Transfer below), and any other required documents; and



either certificates representing the tendered shares or, in the case of tendered shares delivered in accordance with the procedures for book-entry transfer we describe below, a book-entry confirmation of that delivery
(see Book-Entry Transfer below).



if you are a participant in the Companys Employee Stock Purchase Plan (ESPP), you may tender shares that you have purchased through the ESPP. If you have purchased shares through the ESPP and hold such
shares at Computershare Plan Managers, the administrator of our ESPP (the Plan Admin), contact the Plan Admin and request that the Plan Admin tender your shares. You must follow the procedures described in the separate instructions that
you will receive and accept the Offer by 5:00 P.M., New York City Time, on Friday, May 11, 2018, unless the offer is extended.

If a broker, dealer, commercial bank, trust company or other nominee holds your shares, it is likely the nominee has established an earlier
deadline for you to act to instruct the nominee to accept the Offer on your behalf. We urge you to contact your broker, dealer, commercial bank, trust company or other nominee to find out the nominees applicable deadline.

The valid tender of shares by you by one of the procedures described in this Section 3 will constitute a binding agreement between you
and us on the terms of, and subject to the conditions to, the Offer.

In accordance with Instruction 5 of the Letter of Transmittal, each shareholder desiring
to tender shares pursuant to the Offer must either (1) check the box in the section of the Letter of Transmittal captioned Shares Tendered at Cash Price Determined Under the Offer, in which case you will be deemed to have tendered
your shares at the minimum price of $98.00 per share or (2) check one, and only one, of the boxes corresponding to the cash price at which shares are being tendered in the section of the Letter of Transmittal captioned Cash Price (in
Dollars) Per Share at Which Shares Are Being Tendered. A tender of shares will be proper only if one, and only one, of these boxes is checked on the Letter of Transmittal.

If tendering shareholders wish to maximize the chance that their shares will be purchased, they should check the box in the section of the
Letter of Transmittal captioned Shares Tendered at Cash Price Determined Under the Offer. For purposes of determining the cash purchase price, those shares that are tendered by shareholders agreeing to accept the purchase price
determined in the Offer will be deemed to be tendered at the minimum price of $98.00 per share. See Section 8 for recent market prices for the shares. Checking the box captioned Shares Tendered at Cash Price Determined Under the
Offer will increase the possibility that the Cash Purchase Price will be set at $98.00 per share.

If tendering shareholders wish to
indicate a specific price (in multiples of $0.25) at which their shares are being tendered, they must check the applicable price box in the section of the Letter of Transmittal captioned Cash Price (in Dollars) per Share at Which Shares Are
Being Tendered. Tendering shareholders should be aware that this election could mean that none of their shares will be purchased if the cash price selected by the shareholder is higher than the Cash Purchase Price we eventually select after
the Expiration Time.

A shareholder who wishes to tender shares at more than one cash price must complete a separate Letter of Transmittal
for each cash price at which shares are being tendered. The same shares cannot be tendered (unless previously properly withdrawn in accordance with the terms of the Offer) at more than one price. In case of withdrawal, shareholders that tendered
multiple prices pursuant to multiple Letters of Transmittal must comply with the procedures set forth in Section 4.

We urge
shareholders that hold shares through brokers or banks to consult the brokers or banks to determine whether transaction costs are applicable if they tender shares through the brokers or banks and not directly to the Depositary and Paying Agent.

Shareholders who hold shares through the Companys ESPP should be aware that they have an earlier deadline for participation
in the Offer. Accordingly, such shareholders should refer to the separate instructions that they have received or contact the Plan Admin as soon as possible for details with respect to the deadline such shareholder must take action in order to
participate in the Offer.

Odd Lot Holders who tender all their shares must also complete the section captioned Odd Lots
in the Letter of Transmittal to qualify for the preferential treatment available to Odd Lot Holders as set forth in Section 1.

Book-Entry Transfer. For purposes of the Offer, the Depositary and Paying Agent will establish an account for the shares at The
Depository Trust Company (the book-entry transfer facility) within two business days after the date of this Offer to Purchase. Any financial institution that is a participant in the book-entry transfer facilitys system may make
book-entry delivery of shares by causing the book-entry transfer facility to transfer those shares into the Depositary and Paying Agents account in accordance with the book-entry transfer facilitys procedures for that transfer. Although
delivery of shares may be effected through book-entry transfer into the Depositary and Paying Agents account at the book-entry transfer facility, the Letter of Transmittal, properly completed and duly executed, with any required signature
guarantees, or an agents message, and any other required documents must, in any case, be transmitted to, and received by, the Depositary and Paying Agent at one of its addresses set forth on the back cover of this Offer to Purchase prior to
the Expiration Time.

The confirmation of a book-entry transfer of shares into the Depositary and Paying
Agents account at the book-entry transfer facility as we describe above is referred to herein as a book-entry confirmation. Delivery of documents to the book-entry transfer facility in accordance with the book-entry transfer
facilitys procedures will not constitute delivery to the Depositary and Paying Agent.

The term agents
message means a message transmitted by the book-entry transfer facility to, and received by, the Depositary and Paying Agent and forming a part of a book-entry confirmation, stating that the book-entry transfer facility has received an express
acknowledgment from the participant tendering shares through the book-entry transfer facility that the participant has received and agrees to be bound by the terms of the Letter of Transmittal and that we may enforce that agreement against that
participant.

Method of Delivery. The method of delivery of shares, the Letter of Transmittal and all other required documents,
including delivery through the book-entry transfer facility, is at the election and risk of the tendering shareholder. Shares will be deemed delivered only when actually received by the Depositary and Paying Agent (including, in the case of a
book-entry transfer, by book-entry confirmation). If you plan to make delivery by mail, we recommend that you deliver by registered mail with return receipt requested and obtain proper insurance. In all cases, sufficient time should be allowed to
ensure timely delivery.

Signature Guarantees. No signature guarantee will be required on a Letter of Transmittal for shares
tendered thereby if:



the registered holder(s) of those shares signs the Letter of Transmittal and has not completed the box entitled Special Payment Instructions in the Letter of Transmittal; or



those shares are tendered for the account of an eligible institution.

For
purposes hereof, a registered holder of tendered shares will include any participant in the book-entry transfer facilitys system whose name appears on a security position listing as the owner of those shares, and an eligible
institution is a financial institution, which term includes most commercial banks, savings and loan associations and brokerage houses, that is a participant in any of the following: (i) the Securities Transfer Agents Medallion
Program; (ii) the New York Stock Exchange, Inc. Medallion Signature Program; or (iii) the Stock Exchange Medallion Program.

Except as we describe above, all signatures on any Letter of Transmittal for shares tendered thereby must be guaranteed by an eligible
institution. See Instructions 1 and 6 to the Letter of Transmittal. If the certificates for shares are registered in the name of a person other than the signer of the Letter of Transmittal, or if payment is to be made or certificates for shares not
tendered or not accepted for payment are to be returned to a person other than the registered holder of the certificates surrendered, then the tendered certificates must be endorsed or accompanied by appropriate stock powers, in either case signed
exactly as the name or names of the registered holders or owners appear on the certificates, with the signatures on the certificates or stock powers guaranteed as aforesaid. See Instructions 1 and 6 to the Letter of Transmittal.

Shareholders may contact the Information Agent or their broker for assistance. The contact information for the Information Agent is on the
back cover page of this Offer to Purchase.

Return of Unpurchased Shares. The Depositary and Paying Agent will return certificates
for unpurchased shares promptly after the expiration or termination of the Offer or the proper withdrawal of the shares, as applicable, or, in the case of shares tendered by book-entry transfer at the book-entry transfer facility, the Depositary and
Paying Agent will credit the shares to the appropriate account maintained by the tendering shareholder at the book-entry transfer facility, in each case without expense to the shareholder.

Tendering Shareholders Representation and Warranty; Our Acceptance Constitutes an Agreement. It is a violation of Rule 14e-4
promulgated under the Exchange Act for a person acting alone or in concert with others,

directly or indirectly, to tender shares for such persons own account unless at the time of tender and at the Expiration Time such person has a net long position in (a) the
shares that is equal to or greater than the amount tendered and will deliver or cause to be delivered such shares for the purpose of tendering to us within the period specified in the Offer or (b) other securities immediately convertible into,
exercisable for or exchangeable into shares (Equivalent Securities) that is equal to or greater than the amount tendered and, upon the acceptance of such tender, will acquire such shares by conversion, exchange or exercise of such
Equivalent Securities to the extent required by the terms of the Offer and will deliver or cause to be delivered such shares so acquired for the purpose of tender to us within the period specified in the Offer. Rule 14e-4 also provides a similar
restriction applicable to the tender on behalf of another person. A tender of shares made pursuant to any method of delivery set forth herein will constitute the tendering shareholders acceptance of the terms and conditions of the Offer, as
well as the tendering shareholders representation and warranty to us that (a) such shareholder has a net long position in shares or Equivalent Securities at least equal to the shares being tendered within the meaning of Rule
14e-4, and (b) such tender of shares complies with Rule 14e-4. Our acceptance for payment of shares tendered pursuant to the Offer will constitute a binding agreement between the tendering shareholder and us upon the terms and subject to the
conditions of the Offer.

A tender of shares made pursuant to any method of delivery set forth herein will also constitute a
representation and warranty to us that the tendering shareholder has full power and authority to tender, sell, assign and transfer the shares tendered, and that, when the same are accepted for payment by us, we will acquire good, marketable and
unencumbered title thereto, free and clear of all security interests, liens, restrictions, claims, encumbrances, conditional sales agreements and other obligations relating to the sale or transfer of the shares, and the same will not be subject to
any adverse claim or right. Any such tendering shareholder will, on request by the Depositary and Paying Agent or us, execute and deliver any additional documents deemed by the Depositary and Paying Agent or us to be necessary or desirable to
complete the sale, assignment and transfer of the shares tendered, all in accordance with the terms of the Offer.

A properly completed
Letter of Transmittal, and any other documents required by the Letter of Transmittal, must be delivered to the Depositary and Paying Agent and not to us or the Information Agent. All authority conferred or agreed to be conferred by delivery of the
Letter of Transmittal shall be binding on the successors, assigns, heirs, personal representatives, executors, administrators and other legal representatives of the tendering shareholder and shall not be affected by, and shall survive, the death or
incapacity of such tendering shareholder.

Determination of Validity; Rejection of Shares; Waiver of Defects; No Obligation to Give
Notice of Defects. All questions as to the number of shares to be accepted, the price to be paid for shares to be accepted and the validity, form, eligibility (including time of receipt) and acceptance for payment of any tender of shares will be
determined by us, in our sole discretion, and our determination will be final and binding on all persons participating in the Offer, subject to such Offer participants disputing such determination in a court of competent jurisdiction. We
reserve the absolute right prior to the expiration of the Offer to reject any or all tenders we determine not to be in proper form or the acceptance for payment of or payment for which may, in the opinion of our counsel, be unlawful. We also reserve
the absolute right to waive any conditions of the Offer with respect to all shareholders prior to the Expiration Time or any defect or irregularity in any tender with respect to any particular shares or any particular shareholder whether or not we
waive similar defects or irregularities in the case of other shareholders. No tender of shares will be deemed to have been validly made until all defects or irregularities relating thereto have been cured or waived. None of us, the Depositary and
Paying Agent, the Information Agent or any other person will be under any duty to give notification of any defects or irregularities in tenders or incur any liability for failure to give any such notification. Our reasonable interpretation of the
terms of and conditions to the Offer, including the Letter of Transmittal and the instructions thereto, will be final and binding on all persons participating in the Offer, subject to such Offer participants disputing such determination in a
court of competent jurisdiction. By tendering shares to us, you agree to accept all decisions we make concerning these matters and waive any right you might otherwise have to challenge those decisions. We strongly encourage shareholders to submit
completed tender materials as early as possible after you have

properly considered the information in this Offer to Purchase, so that you will have as much time as possible prior the Expiration Time to correct any defects or irregularities in the materials
you provide to us.

Backup Withholding. Under the U.S. backup withholding rules, the applicable withholding agent may be required
to withhold the applicable statutory percentage (currently 24%) of certain reportable payments payable to a shareholder or other payee pursuant to the Offer, unless the shareholder or other payee provides its taxpayer identification number (employer
identification number or social security number) to the Depositary and Paying Agent and certifies that such number is correct and that it is not subject to backup withholding or an exemption otherwise applies under applicable Treasury regulations
and the shareholder appropriately certifies that it qualifies for such exemption. Therefore, except as provided below, each tendering shareholder that is a U.S. Holder (as defined in Section 14) should complete and sign the IRS Form W-9
included as part of the Letter of Transmittal and available on the IRS website so as to provide the information and certification necessary to avoid backup withholding. Backup withholding is not an additional tax. Rather, the amount of backup
withholding can be refunded by the IRS or credited against the U.S. federal income tax liability of the person subject to backup withholding, provided the required information is timely furnished to the IRS. Certain payments made to holder pursuant
to the Offer may also be subject to information reporting to the Internal Revenue Service.

Certain shareholders (including, among others,
certain corporations and certain foreign individuals and entities) are not subject to backup withholding. In order for an exempt Non-U.S. Holder to qualify as a recipient exempt from backup withholding, that shareholder must submit a statement
(generally, an IRS Form W-8BEN or other applicable IRS Form W-8 available on the IRS website), signed under penalties of perjury, attesting to that shareholders exempt status. Such statements can be obtained from the Depositary and Paying
Agent or from the IRS at www.irs.gov. In order for an exempt U.S. Holder to qualify as a recipient exempt from backup withholding, that shareholder must submit an IRS Form W-9, signed under penalties of perjury, attesting to that shareholders
exempt status.

Any taxes withheld pursuant to these backup withholding rules or otherwise will be treated for all purposes as having been
paid to the persons with respect to whom such amounts were withheld.

Holders are urged to consult their own tax advisors to determine
whether they are exempt from these backup withholding and reporting requirements.

ANY TENDERING SHAREHOLDER OR OTHER PAYEE THAT FAILS TO
COMPLETE FULLY AND SIGN THE IRS FORM W-9 INCLUDED IN THE LETTER OF TRANSMITTAL OR APPLICABLE IRS FORM W-8 MAY BE SUBJECT TO REQUIRED U.S. BACKUP WITHHOLDING AT THE APPLICABLE STATUTORY RATE (CURRENTLY EQUAL TO 24%) OF THE GROSS PROCEEDS PAID TO SUCH
SHAREHOLDER OR OTHER PAYEE PURSUANT TO THE OFFER.

Lost Certificates. If the share certificates which a registered holder wants to
surrender have been lost, destroyed or stolen, the shareholder should promptly notify the Depositary and Paying Agent at 1-800-356-2017. The Depositary and Paying Agent will instruct the shareholder as to the steps that must be taken in order to
replace the certificates.

4. Withdrawal Rights

Except as this Section 4 otherwise provides, tenders of shares are irrevocable. You may withdraw shares that you have previously tendered
in the Offer according to the procedures we describe below at any time prior to the Expiration Time. You may also withdraw your previously tendered shares at any time after 12:00 midnight, New York City time, on June 14, 2018, unless such
shares have been accepted for payment as provided in the Offer.

For a withdrawal to be effective, a written notice of withdrawal must:



be received in a timely manner by the Depositary and Paying Agent at one of its addresses set forth on the back cover of this Offer to Purchase; and



specify the name of the person having tendered the shares to be withdrawn, the number of shares to be withdrawn and the name of the registered holder of the shares to be withdrawn, if different from the name of the
person who tendered the shares.

If certificates for shares have been delivered or otherwise identified to the Depositary
and Paying Agent, then, prior to the physical release of those certificates, the serial numbers shown on those certificates must be submitted to the Depositary and Paying Agent and, unless an eligible institution has tendered those shares, an
eligible institution must guarantee the signatures on the notice of withdrawal.

If a shareholder has used more than one Letter of
Transmittal or has otherwise tendered shares in more than one group of shares, the shareholder may withdraw shares using either separate notices of withdrawal or a combined notice of withdrawal, so long as the information specified above is
included.

If shares have been delivered in accordance with the procedures for book-entry transfer described in Section 3, any notice
of withdrawal must also specify the name and number of the account at the book-entry transfer facility to be credited with the withdrawn shares and otherwise comply with the book-entry transfer facilitys procedures.

Withdrawals of tenders of shares may not be rescinded, and any shares properly withdrawn will thereafter be deemed not validly tendered for
purposes of the Offer. Withdrawn shares may be retendered at any time prior to the Expiration Time by again following one of the procedures described in Section 3.

We will decide, in our sole discretion, all questions as to the form and validity, including time of receipt, of notices of withdrawal, and
each such decision will be final and binding on all persons participating in the Offer, subject to such other participants disputing such determination in a court of competent jurisdiction. We also reserve the absolute right to waive any
defect or irregularity in the withdrawal of shares by any shareholder, whether or not we waive similar defects or irregularities in the case of any other shareholder. None of the Company, the Depositary and Paying Agent, the Information Agent or any
other person will be under any duty to give notification of any defects or irregularities in any notice of withdrawal or incur any liability for failure to give any such notification.

Our reservation of the right to delay payment for shares which we have accepted for payment is limited by Rule 13e-4(f)(5) and Rule 14e-1(c)
under the Exchange Act, which require that we must pay the consideration offered or return the shares tendered promptly after termination or withdrawal of a tender offer.

5. Purchase of Shares and Payment of Cash Purchase Price

Upon the terms and subject to the conditions of the Offer, promptly following the Expiration Time, we will accept for payment and pay the Cash
Purchase Price, less any applicable withholding and without interest, and as adjusted for any stock split, and thereby purchase shares properly tendered and not properly withdrawn for an aggregate Cash Purchase Price of up to $600 million. We may
increase the number of shares accepted for payment in the Offer by no more than 2% of the outstanding shares without extending the Offer. See Section 1.

Upon the terms and subject to the conditions of the Offer, promptly after the Expiration Time we will determine a single per share cash price,
which will be not greater than $108.00 nor less than $98.00 per share, net to the seller in cash, less any applicable tax withholding and without interest, and as adjusted for any stock split, that we will pay for shares properly tendered, for an
aggregate Cash Purchase Price of up to $600 million. The Cash Purchase Price will be the lowest price per share of not greater than $108.00 nor less than $98.00 per share

(in multiples of $0.25), as adjusted for any stock split, at which shares have been properly tendered in the Offer, that will enable us to purchase the maximum number of shares for an aggregate
Cash Purchase Price of up to $600 million. If fewer than such number of shares as would enable us to purchase shares pursuant to the Offer for an aggregate Cash Purchase Price of up to $600 million are properly tendered, we will select the lowest
price that will allow us to buy all the shares that are properly tendered.

All shares we acquire in the Offer will be acquired at the
same Cash Purchase Price regardless of whether you tendered your shares at a lower cash price. We will not purchase any shares from shareholders that do not properly tender any of their common shares pursuant to the Offer prior to the Expiration
Time. Subject to the conditions of the Offer, only shares properly tendered, or deemed properly tendered, at prices at or below the Cash Purchase Price will be eligible for purchase in the Offer. If our purchase of all shares properly tendered at or
below the Cash Purchase Price and not properly withdrawn in the Offer would result in aggregate Cash Purchase Price of more than $600 million, we will purchase all shares properly tendered at or below the Cash Purchase Price on a pro rata basis,
except for odd lots (lots held by owners of less than 100 shares at the Expiration Time), which we will purchase on a priority basis, and except for each conditional tender whose condition was not met, which we will not purchase.
Tendering shareholders will receive a cash payment only if their tendered shares are purchased. Shares tendered but not purchased pursuant to the Offer will be returned to the tendering shareholders at our expense promptly after the Expiration Time.

For purposes of the Offer, we will be deemed to have accepted for payment (and therefore purchased), subject to the odd lot
priority, proration and conditional tender provisions of this Offer, shares that are properly tendered at or below the Cash Purchase Price, only when, as and if we give oral or written notice to the Depositary and Paying Agent of our acceptance of
the shares for payment pursuant to the Offer.

Upon the terms and subject to the conditions of the Offer, we will accept for payment and
pay the per share Cash Purchase Price for each of the shares accepted for payment pursuant to the Offer promptly after the Expiration Time. In all cases, payment for shares tendered and accepted for payment pursuant to the Offer will be made
promptly, subject to possible delay in the event of proration, but only after timely receipt by the Depositary and Paying Agent of:



certificates for shares, or a timely book-entry confirmation of the deposit of shares into the Depositary and Paying Agents account at the book-entry transfer facility,



a properly completed and duly executed Letter of Transmittal, or, in the case of a book-entry transfer, an agents message, and



any other required documents.

We will respectively pay for shares purchased pursuant to the
Offer by depositing the aggregate Cash Purchase Price for the shares with the Depositary and Paying Agent, which will act as agent for tendering shareholders for the purpose of receiving payment from us and transmitting payment to the tendering
shareholders.

In the event of proration, we will determine the proration factor and pay for those tendered shares accepted for payment
promptly after the Expiration Time. However, we expect that we will not be able to announce the final results of any proration or commence payment for any shares purchased pursuant to the Offer until up to ten business days after the Expiration
Time. Certificates for all shares tendered and not purchased, including all shares tendered at prices in excess of the Cash Purchase Price and shares not purchased due to proration or conditional tender will be returned or, in the case of shares
tendered by book-entry transfer, will be credited to the account maintained with the book-entry transfer facility by the participant who delivered the shares, to the tendering shareholder at our expense promptly after the Expiration Time or
termination of the Offer.

Under no circumstances will we pay interest on the Cash Purchase Price, including but not limited to, by
reason of any delay in making payment. In addition, if certain events occur, we may not be obligated to purchase shares pursuant to the Offer. See Section 7.

We will pay all stock transfer taxes, if any, payable on the transfer to us of shares
purchased pursuant to the Offer. If, however, payment of the Cash Purchase Price is to be made to, or (in the circumstances permitted by the Offer) if unpurchased shares are to be registered in the name of, any person other than the registered
holder, or if tendered certificates are registered in the name of any person other than the person signing the Letter of Transmittal, the amount of all stock transfer taxes, if any (whether imposed on the registered holder or the other person),
payable on account of the transfer to the person will be deducted from the Cash Purchase Price unless satisfactory evidence of the payment of the stock transfer taxes, or exemption from payment of the stock transfer taxes, is submitted. See
Instruction 7 of the Letter of Transmittal.

The number of common shares subject to the Offer and the price per share relate to the common
shares as outstanding on the date of the Offer. The Expiration Time is currently scheduled two days after the stock split distribution date (May 14, 2018), when the Company expects to effect a two-for-one stock split as described in the
Companys 2018 proxy statement. Following the stock split, the Cash Purchase Price will be adjusted ratably to account for the increased number of common shares outstanding on a post-split basis. See Section 8.

6. Conditional Tender of Shares

Subject to the exception for Odd Lot Holders, in the event of an over-subscription of the Offer, shares properly tendered at or below the Cash
Purchase Price will be subject to proration. See Section 1. As discussed in Section 14, the number of shares to be purchased from a particular shareholder may affect the tax treatment of the purchase to the shareholder and the
shareholders decision whether to tender. Accordingly, a shareholder may tender shares subject to the condition that a specified minimum number of the shareholders shares tendered pursuant to a Letter of Transmittal must be purchased if
any shares tendered are purchased. Any shareholder desiring to make a conditional tender must so indicate in the box entitled Conditional Tender in the Letter of Transmittal.

Any tendering shareholder wishing to make a conditional tender must calculate and appropriately indicate the minimum number of shares that
must be purchased if any are to be purchased. After the Offer expires, our purchase of all shares properly tendered at or below the Cash Purchase Price and not properly withdrawn would result in an aggregate Cash Purchase Price of more than $600
million, so that we must prorate our acceptance of and payment for tendered shares, we will calculate a preliminary proration percentage based upon all shares properly tendered, conditionally or unconditionally. If the effect of this preliminary
proration would be to reduce the number of shares to be purchased from any shareholder below the minimum number specified in a conditional tender, the tender will automatically be regarded as withdrawn (except as provided in the next paragraph). All
shares tendered by a shareholder subject to a conditional tender and regarded as withdrawn as a result of proration will be returned at our expense, promptly after the Expiration Time.

After giving effect to these withdrawals, we will accept the remaining shares properly tendered, conditionally or unconditionally, on a pro
rata basis, if necessary. If conditional tenders would otherwise be regarded as withdrawn and would cause the aggregate Cash Purchase Price to be paid in the Offer to fall below $600 million then, to the extent feasible, we will select enough of the
conditional tenders that would otherwise have been withdrawn to permit us to purchase common shares for an aggregate Cash Purchase Price of up to $600 million. In selecting among the conditional tenders, we will select by random lot, treating all
tenders by a particular taxpayer as a single lot, and will limit our purchase in each case to the designated minimum number of shares to be purchased. To be eligible for purchase by random lot, shareholders whose shares are conditionally tendered
must have tendered all of their shares.

7. Conditions of the Tender Offer

Notwithstanding any other provision of the Offer, we will not be required to accept for payment, purchase or pay for any shares tendered, and
may, at any time, terminate or amend the Offer or may postpone the acceptance for payment of, or the purchase of and the payment for shares tendered, subject to the applicable rules under the

Exchange Act, if at any time prior to the Expiration Time any of the following events has occurred (or shall have been reasonably determined by us to have occurred) that, in our reasonable
judgment and regardless of the circumstances giving rise to the event or events (other than any such event or events that are proximately caused by our action or failure to act), make it inadvisable to proceed with the Offer or with acceptance for
payment:



there has occurred any change in the general political, market, economic or financial conditions in the United States or abroad that we deem is reasonably likely to materially and adversely affect the Companys

As of April 16, 2018, there were 88,202,255 common shares outstanding. On April 17, 2018, the last
full trading day before we commenced the Offer, the last reported sales price of the shares quoted on the NYSE was $103.02 per share, which is greater than the low end of the price range for the Offer of $98.00 per share. We urge
shareholders to obtain a current market price for the shares before deciding whether and at what purchase price or purchase prices to tender their shares.

Dividends. During the second quarter of 2007, our Board adopted a regular quarterly cash dividend program. Our Board authorized a $0.10
per common share dividend each quarter from the adoption of the program through the second quarter of 2010. On August 2, 2010, our Board approved an increase in the quarterly cash dividend to $0.13 per common share, an increase of
$0.03 per common share from prior quarters. On May 2, 2011, we announced that our Board approved an increase in the quarterly cash dividend to $0.20 per common share, an increase of $0.07 per common share from prior quarters. On
February 21, 2012, we announced that our Board approved an increase in the quarterly cash dividend to $0.30 per common share, an increase of $0.10 per common share from prior quarters. On April 28, 2014, we announced that our Board
approved terminating our quarterly cash dividend and instead utilizing the cash to repurchase additional common shares. There were no dividends paid and declared during fiscal years 2015, 2016, 2017 or the first quarter of 2018.

The declaration of future dividends is subject to the discretion of our Board and will depend upon various factors, including our earnings,
financial condition, our available distributable reserves under Cayman Islands law, restrictions imposed by the Credit Facility, as amended, and the terms of any other indebtedness that may be outstanding, cash requirements, future prospects and
other factors deemed relevant by our Board.

Stock Split. As previously announced, the Board has approved, and is currently
soliciting shareholder approval of a two-for-one stock split of the common shares. If the stock split is approved by the affirmative vote of a majority of common shares present or represented by proxy and entitled to vote on such stock split
proposal on April 24, 2018 at the Companys Annual General Meeting of Shareholders (the Annual Meeting), then on May 7, 2018 (the stock split record date) each issued and outstanding common share, par value US
$0.001 per share, would be subdivided into two common shares, par value US $0.0005 per share, and the Companys

currently authorized share capital of 1,000,000,000 common shares, par value US $0.001 per share, would be subdivided into 2,000,000,000 common shares, par value US $0.0005 per share (the
stock split). Assuming the stock split is approved by shareholders on April 24, 2018, the Company expects to distribute the additional common shares in connection with the stock split on or about May 14, 2018 (the stock
split distribution date) and expects the common shares will go ex-dividend the following day on May 15, 2018 (the stock split ex-dividend date). See Section 10 for information regarding the Companys Definitive Proxy
Statement, March 13, 2018, containing a more detailed description of the proposed stock split.

The stock split distribution date for
the stock split is currently scheduled two days prior to the Expiration Time. All Offer terms, including the Cash Purchase Price, described herein are based on the pre-stock split number of common shares outstanding, as well as on the prevailing
trading price for the common shares in the market before the completion of the stock split. Following the stock split, the Cash Purchase Price will be adjusted ratably to account for the increased number of common shares outstanding on a post-split
basis. By way of example only, if the Cash Purchase Price in the Offer was determined to be $100.00 per share, net to the seller in cash, less any applicable tax withholding and without interest, on a pre-stock split basis, and you tendered 100
common shares, and the stock split were to be approved at the Annual Meeting, the Cash Purchase Price would be adjusted ratably to $50.00 per share, net to the seller in cash, less any applicable tax withholding and without interest, and the number
of common shares tendered would be 200 common shares.

Shareholders should complete the Letter of Transmittal (and any other documents
used to tender common shares) specifying the number of common shares, and the cash purchase price(s) per share, they are tendering in the Offer on a pre-stock split basis. See Instruction 5 of the Letter of Transmittal.

Share Repurchases. On February 21, 2017, our Board authorized a new three-year $1.5 billion share repurchase program that will
expire on February 21, 2020, which replaced our prior share repurchase authorization that was set to expire on June 30, 2017. As of April 16, 2018, the Company had approximately $713.3 million of remaining authorized capacity. This
share repurchase program allows the Company and its wholly owned subsidiaries, including HBL Swiss, to repurchase shares, at such times and prices as determined by the Companys management, as market conditions warrant, and to the extent our
distributable reserves are available under Cayman Islands law. The Credit Facility permits the Company to repurchase shares as long as no default or event of default exists and other conditions such as specified consolidated leverage ratios are met.

We did not repurchase any common shares in the open market during the year ended December 31, 2016. During the year ended
December 31, 2017, Herbalife Ltd. purchased approximately 6.7 million shares in the Prior Offer at an aggregate cost of approximately $457.8 million, or an average cost of $68.00 per share. In addition, during the year ended
December 31, 2017 and the three months ended March 31, 2018, HBL Swiss purchased approximately 5.0 million shares through open market purchases at an aggregate cost of approximately $328.9 million, or an average cost of
$65.62 per share. Although these shares are owned by an indirect wholly owned subsidiary of the Company, they are reflected as treasury shares under U.S. GAAP and therefore reduce the number of common shares outstanding within the
Companys condensed consolidated financial statements and the weighted-average number of common shares outstanding used in calculating earnings per share. The shares held by HBL Swiss, however, remain outstanding on the books and records of the
Companys transfer agent and therefore still carry voting and other share rights related to ownership of the shares, which may be exercised. Following the Prior Offer, on October 25, 2017, HBL Swiss filed a Schedule 13G disclosing its
aggregate beneficial ownership and noting the common shares held by HBL Swiss will be voted in the same manner, and to the maximum extent possible, in the same proportion, as all other votes cast with respect to any matter properly submitted to a
vote of the Companys shareholders, so long as it is consistent with applicable laws. As of April 16, 2018, the Company held approximately 5.0 million of treasury shares for U.S. GAAP purposes.

The number of shares issued upon vesting or exercise for certain restricted stock units and SARs granted pursuant to the Companys
share-based compensation plans is net of the statutory withholding requirements that

the Company pays on behalf of its employees. Although shares withheld are not issued, they are treated as common share repurchases in the Companys condensed consolidated financial
statements and reduce the Companys additional paid-in-capital within total shareholders equity and are reflected as share repurchases on the Companys condensed consolidated statements of cash flows as they reduce the number of
shares that would have been issued upon vesting. These shares do not count against the authorized capacity under the Companys share repurchase program described above.

9. Source and Amount of Funds

The maximum aggregate Cash Purchase Price the Company will pay to purchase common shares pursuant to the Offer is $600 million. The Company
anticipates that it will pay for such shares tendered from the proceeds from the $1,300.0 million term loan under its Credit Facility, cash on hand, and/or drawings under its $150.0 million revolving credit facility. As a result, it will have
reduced liquidity. Reduced liquidity could have certain material adverse effects on the Company, including, but not limited to, the following: (i) the Companys available liquidity in the future for acquisitions, working capital, capital
expenditures, and general corporate or other purposes could be impaired, and additional financing may not be available on terms acceptable to the Company; (ii) the Companys ability to withstand competitive pressures may be decreased; and
(iii) the Companys reduced level of liquidity may make it more vulnerable to economic downturns, and reduce its flexibility in responding to changing business, regulatory and economic conditions. However, after the Offer is completed, the
Company believes that its then-available cash and cash equivalents, cash flow from operations and investing activities and access to capital will continue to provide it with adequate financial resources to meet its working capital requirements and
to fund capital expenditures as well as to engage in strategic activities.

Consummation of the Offer is not subject to any financing
condition, but is subject to certain other conditions. See Section 7.

10. Information About the
Company

The Company is a global nutrition company founded in 1980 that develops and sells weight-management, targeted nutrition,
energy, sports & fitness, and outer nutrition care products. As of December 31, 2017, the Company sold its products in 94 countries. We believe the enhanced consumer awareness and the demand for our products due to the global obesity
epidemic coupled with the effectiveness of network marketing have been the primary reasons for our success throughout our 38-year operating history.

We believe that direct-selling is ideally suited to marketing our products because sales of weight management, targeted nutrition, energy,
sports & fitness, and outer nutrition products are strengthened by ongoing personal contact and support, coaching and education between our members and their customers towards a healthy and active lifestyle.

11. Interest of Directors and Executive Officers; Transactions and Arrangements Concerning the Shares

Our directors and executive officers are entitled to participate in the Offer on the same basis as all other shareholders. None of the
directors or executive officers of the Company intend to tender any of their shares in the Offer. In addition, the directors and executive officers of the Company and the Icahn Entities are prohibited from purchasing or otherwise acquiring any
common shares until the expiration of ten business days after the date of termination of the Offer, as required by Rules 13e-4(f)(6) and 14e-5 under the Exchange Act.

Additionally, in connection with the Prior Offer, the Company entered into the Icahn Letter Agreement with the Icahn Entities. Pursuant to the
Icahn Letter Agreement, the Icahn Entities agreed, among other things, that for the two years following commencement of the Offer, the Icahn Entities will not purchase or otherwise acquire common shares that would increase their aggregate beneficial
ownership above 50% of the outstanding common shares unless they have agreed to acquire 100% of the outstanding common shares. Notwithstanding the foregoing, for the purposes of the Icahn Letter Agreement, the Icahn Entities will be deemed not to
have increased their aggregate beneficial ownership above 50% of the outstanding common shares if the increase in their aggregate beneficial ownership percentage occurs as a result of a reduction in the number of outstanding common shares. Thus, any
future repurchase of shares by the Company, either as part of Herbalifes current share repurchase program or otherwise, could have the potential effect of increasing the Icahn Entities beneficial ownership above 50% of the outstanding
common shares without the Icahn Entities being required to acquire 100% of the outstanding common shares pursuant to the Icahn Letter Agreement.

The following table shows the beneficial ownership of the common shares as of the date of
this Offer to Purchase of each person who we know beneficially owns more than 5% of the common shares, the directors and named executive officers of the Company, and all of the directors and executive officers as a group. Beneficial ownership, which
is determined in accordance with the rules and regulations of the SEC, means the sole or shared power to vote or direct the voting or to dispose or direct the disposition of the common shares. The percentage of the common shares beneficially owned
by a person assumes that the person has exercised all options, and converted all convertible securities, the person holds that are exercisable or convertible within 60 days of the date of April 16, 2018, and that no other persons exercised
any of their options or converted any of their convertible securities. Except as otherwise indicated in the footnotes to the table or in cases where community property laws apply, we believe that each person identified in the table possesses sole
voting and investment power over all common shares shown as beneficially owned by the person. Except as otherwise indicated, the business address for each of the following persons is 800 West Olympic Boulevard, Suite 406, Los Angeles,
California 90015.

Applicable percentage is based upon (i) 83,190,015 Common Shares outstanding as of April 16, 2018, which pursuant to Instruction 1 to Item 403 of
Regulation S-K, excludes 5,012,510 Common Shares held by HBL Swiss Financing GmbH, an indirect wholly owned subsidiary of the Company, which are considered to be outstanding under Cayman Islands law and
carry voting and other share rights related to ownership of our Common Shares, which may be exercised, and (ii) the relevant number of Common Shares issuable upon exercise of stock options or other awards which are exercisable or have vested or
will be exercisable or will vest within 60 days of April 16, 2018. Beneficial ownership is determined in accordance with the rules of the SEC, and includes voting and investment power with respect to Common Shares. Except as otherwise
indicated below, to our knowledge, all persons listed above have sole voting and investment power with respect to their Common Shares, except to the extent authority is shared by spouses under applicable law.

controlling entity or of our subsidiaries, has effected any transactions involving the Shares during the 60 days prior to the date hereof, except for the following transactions:

12. Effects of the Tender Offer on the Market for Shares;
Registration under the Exchange Act

The completion of the Offer in accordance with its terms and conditions will not cause the
Company to stop being quoted on the NYSE or to stop being subject to the periodic reporting requirements of the Exchange Act.

However,
the purchase by us of shares under the Offer will reduce the number of shares that might otherwise be traded publicly and is likely to reduce the number of shareholders. As a result, trading of a relatively small volume of the shares and limited
liquidity after consummation of the Offer may have a greater impact on trading prices than would be the case prior to consummation of the Offer with an increase in price volatility. Shareholders may not be able to sell non-tendered shares in the
future on the NYSE or otherwise, at a net price higher than the Cash Purchase Price in the Offer. We can give no assurance as to the price at which a shareholder may be able to sell his or her shares in the future.

13. Legal Matters; Regulatory Approvals

We are not aware of any license or regulatory permit that is material to the Companys business that might be adversely affected by our
acquisition of shares as contemplated by the Offer or of any approval or other action by any government or governmental, administrative or regulatory authority or agency, domestic, foreign or supranational, that would be required for the acquisition
or ownership of shares by us as contemplated by the Offer that is material to the success of the Offer. Should any such approval or other action be required, we presently contemplate that we will seek that approval or other action where practicable
if practicable within the time period contemplated by the Offer. We are unable to predict whether we will be required to delay the acceptance for payment of or payment for shares tendered under the Offer pending the outcome of any such matter. There
can be no assurance that any such approval or other action, if needed, would be obtained or would be obtained without substantial cost or conditions or that the failure to obtain the approval or other action might not result in adverse consequences
to its business and financial condition. Our obligations under the Offer to accept for payment and pay for shares is subject to certain conditions. See Section 7.

14. Certain Material U.S. Federal Income Tax Consequences of the Offer

The following summary describes certain material U.S. federal income tax consequences to U.S. Holders (as defined below) of the exchange of
shares for cash pursuant to the Offer. This discussion is based upon the Code, existing and proposed Treasury Regulations, administrative pronouncements and judicial decisions, all as in effect as of the date hereof and any changes to which could
materially affect the tax consequences described herein and could be made on a retroactive basis.

This discussion deals only with U.S.
Holders who hold their shares as capital assets for U.S. federal income tax purposes and does not address all tax consequences, including tax consequences that may be relevant to various specified categories of holders (such as dealers in securities
or commodities, traders in securities that elect to mark their holdings to market, financial institutions, regulated investment companies, real estate investment trusts, holders whose functional currency is not the U.S. dollar, insurance companies,
pass-through entities, tax-exempt organizations, certain former citizens or long-term residents of the United States, holders who beneficially own directly, indirectly, or constructively (including based on the application of certain attribution
rules under the Code) more than 5% of the Companys outstanding shares by vote or value (as determined for income tax purposes), or holders who hold shares as part of a hedging, integrated, conversion or constructive sale transaction or as a
position in a straddle). In particular, different rules may apply to shares acquired as compensation (including shares acquired upon the exercise of employee stock options or otherwise as compensation). This discussion does not address the
application of the alternative minimum tax or the state, local or non-U.S. tax consequences of participating in the Offer. Holders of shares should consult their tax advisors as to the particular consequences to them of participation in the Offer.

As used herein, a U.S. Holder means a beneficial holder of shares that is for U.S. federal income tax purposes: (a) an
individual citizen or resident of the United States, (b) a corporation (or other entity treated as a

corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States, any state thereof or the District of Columbia, (c) an estate the income of
which is subject to U.S. federal income taxation regardless of its source, or (d) a trust if (i) a court within the United States can exercise primary supervision of the trusts administration and one or more U.S. persons have the
authority to control all substantial decisions of the trust or (ii) it has a valid election in effect under applicable regulations to be treated as a U.S. person.

If a partnership (including for this purpose any entity or arrangement, domestic or foreign, treated as a partnership for U.S. federal income
tax purposes) beneficially owns shares, the tax treatment of a partner generally will depend upon the status of the partner and the activities of the partnership. Beneficial owners that are partnerships, and partners in such partnerships, should
consult their own tax advisors.

This discussion is for general information only and should not be construed as tax advice. It is a
summary and does not purport to be a comprehensive analysis or description of all potential U.S. federal income tax consequences of the Offer. We urge you to consult your tax advisor with respect to the particular U.S. federal, state and local or
foreign tax consequences of the Offer to you.

Participation in the Offer

The receipt of the Cash Purchase Price for the shares pursuant to the Offer will generally be a taxable transaction for U.S. federal income tax
purposes. A holder that participates in the Offer will be treated, depending on such holders particular circumstances, either as recognizing gain or loss from the disposition of the shares or as receiving a distribution in respect of shares
for U.S. federal income tax purposes.

In general under applicable U.S. federal income tax laws, a holder of corporate stock that receives
a payment from the issuer in redemption of all or a portion of such stock will be treated as having received a distribution taxable as a dividend to the extent of the issuers earnings and profits. However, a holder will recognize gain or loss
on an exchange of shares for cash if the exchange (a) results in a complete termination of all such holders equity interest in the Company, (b) results in a substantially disproportionate redemption with
respect to such holder, or (c) is not essentially equivalent to a dividend with respect to the holder.

If one of these
requirements is met then the redemption will not be treated as a dividend but instead as a taxable exchange of the shares by such holders generally resulting in capital gain or loss. In applying the relevant test, a holder must take into account
shares that such holder constructively owns under certain attribution rules, pursuant to which the holder will be treated as owning shares owned by certain family members (except that in the case of a complete termination a holder may
waive, under certain circumstances, attribution from family members) and related entities and shares that the holder has the right to acquire by exercise of an option.

The exchange of shares for cash by a holder pursuant to the Offer will result in a complete termination of the holders stock interest in
the Company if either (a) all of the shares actually and constructively owned by the holder are exchanged for cash pursuant to the Offer or (b) all of the shares actually owned by the holder are exchanged for cash pursuant to the Offer and
the holder is eligible to waive, and effectively waives the attribution of shares constructively owned by the holder in accordance with the rules described in section 302(c)(2) of the Internal Revenue Code.

An exchange of shares for cash will be a substantially disproportionate redemption with respect to a holder if the percentage of the
then-outstanding shares owned by such holder in the Company immediately after the exchange is less than 80% of the percentage of the shares owned by such holder in the Company immediately before the exchange. If an exchange of shares for cash fails
to satisfy the substantially disproportionate test, the holder nonetheless may satisfy the not essentially equivalent to a dividend test. An exchange of shares for cash will satisfy the not essentially equivalent to a
dividend test if it results in a meaningful reduction of the holders equity interest in the Company. Whether an exchange results in a meaningful reduction of the holders

equity interest in the Company will depend on the holders particular facts and circumstances. However, the Internal Revenue Service (IRS) has indicated in published rulings that
even a small reduction in the proportionate interest of a small minority shareholder in a publicly held corporation who does not exercise any control over or participate in the management of corporate affairs may constitute such a meaningful
reduction.

We cannot predict whether, or the extent to which, the Offer will be over-subscribed. If the Offer is over-subscribed,
proration of tenders pursuant to the Offer will cause us to accept fewer shares than are tendered. Therefore, a beneficial holder can be given no assurance that a sufficient number of such beneficial holders shares will be purchased pursuant
to the Offer to ensure that such purchase will be treated as a sale or exchange, rather than as a distribution, for U.S. federal income tax purposes pursuant to the rules discussed above.

Exchange Treatment. Assuming that no portion of the amount that a U.S. Holder receives pursuant to this Offer is treated as a
distribution, the exchange of shares pursuant to the Offer will be treated as sale or exchange for U.S. federal income tax purposes.

Treatment as Open Transaction. Subject to the discussion below regarding the passive foreign investment company rules, if the
transaction is treated as an open transaction for U.S. federal income tax purposes, a U.S. Holder generally will recognize capital gain or loss upon consummation of the Offer in an amount equal to the difference, if any, between the
amount of cash received and such U.S. holders adjusted tax basis in the shares tendered pursuant the Offer. Gain or loss recognized in the transaction must be determined separately for each identifiable block of shares tendered pursuant the
Offer (i.e., shares acquired at the same cost in a single transaction). Any such gain or loss will be long-term capital gain if the shares were held for more than one year prior to such disposition. The deductibility of capital losses is subject to
certain limitations.

Distribution Treatment. If a U.S. Holders exchange of shares for cash pursuant to the Offer does not
constitute a sale or exchange for U.S. federal income tax purposes, the receipt of cash by such U.S. Holder pursuant to the Offer will generally be treated as a distribution, and the U.S. Holders tax basis in the shares exchanged generally
will be added to any shares retained by the U.S. Holder.

Subject to the discussion of the passive foreign investment company rules, the
distribution will be treated as a dividend to the extent of the Companys current and accumulated earnings and profits, as determined under United States federal income tax principles. Such dividends will not be eligible for the dividends
received deduction allowed to corporations in respect of dividends received from other U.S. corporations under the Code. With respect to non-corporate U.S. Holders, certain dividends received from a qualified foreign corporation may be subject to
reduced rates of taxation. A foreign corporation is treated as a qualified foreign corporation with respect to dividends paid by that corporation on shares that are readily tradable on an established securities market in the United States. We expect
our common shares to be considered readily tradable on an established securities market, though there can be no assurances. However, even if our common shares are readily tradable on an established securities market in the United States, we will not
be treated as a qualified foreign corporation if we are a PFIC (as such term is defined below) for the taxable year in which we pay the dividend or were a PFIC for the preceding taxable year. Non-corporate holders that do not meet a minimum holding
period requirement during which they are not protected from a risk of loss or that elect to treat the dividend income as investment income pursuant to Section 163(d)(4) (B) of the Code will not be eligible for the reduced rates
of taxation regardless of our status as a qualified foreign corporation. For this purpose, the minimum holding period requirement will not be met if a share has been held by a holder for 60 days or less during the 121-day period beginning on the
date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend, appropriately reduced by any period in which such holder is protected from risk of loss. In addition, the rate reduction will not apply to
dividends if the recipient of a dividend is obligated to make related payments with respect to positions in substantially similar or related property. This disallowance applies even if the minimum holding period has been met. You should consult your
own tax advisors regarding the availability of the reduced tax rate on dividends in light of your particular circumstances.

To the extent that the amount of the distribution exceeds the Companys current and
accumulated earnings and profits, the excess first will be treated as a return of capital that will reduce the U.S. Holders adjusted tax basis in its shares (but not below zero), and any remaining portion will be taxable as capital gain. Any
such capital gain will be long-term capital gain if the U.S. Holders holding period for the shares at the time of the exchange exceeds one year.

Passive Foreign Investment Company Rules. We believe that we will not be considered a passive foreign investment company
(PFIC) for U.S. federal income tax purposes for our current taxable year and that we have not been a PFIC for prior taxable years. However, since PFIC status depends upon the composition of a companys income and assets and the
market value of its assets from time to time, there can be no assurance that we will not be considered a PFIC for the current taxable year. If we are treated as a PFIC for any taxable year during which a U.S. Holder held shares purchased pursuant to
the Offer, certain adverse consequences could apply to such U.S. Holder. If we are a PFIC for the current taxable year (or were a PFIC for the prior taxable year), the 20% dividend rate discussed above with respect to dividends paid to non-corporate
holders would not apply to any dividend income resulting from the Offer. In addition, if we were a PFIC for any taxable year during which a U.S. Holder held shares purchased pursuant to the Offer, the U.S. Holder would be subject to special rules
with respect to any gain, and any distribution if it is treated as an excess distribution, resulting from the purchase of shares pursuant to the Offer, unless the U.S. Holder makes a mark-to-market election as discussed below. If the
amount received by a U.S. Holder pursuant to the Offer is treated as a distribution and such amount, together with any other distributions received from us during the current year, is greater than 125% of the average annual distributions the U.S.
Holder received with respect to the shares during the shorter of the three preceding taxable years or the U.S. Holders holding period for the Shares, the distribution resulting from the Offer will be treated as an excess distribution. Under
these special tax rules:



the excess distribution or gain will be allocated ratably over the U.S. Holders holding period for the shares;



the amount allocated to the current taxable year, and any taxable year prior to the first taxable year in which the company became a PFIC, will be taxed as ordinary income; and



the amount allocated to each other year will be subject to the highest tax rate in effect for individuals, or corporations, as appropriate, for that year and the interest charge generally applicable to underpayments of
tax will be imposed on the resulting tax attributable to each such year.

The tax liability for amounts allocated to years
prior to the current taxable year cannot be offset by any net operating losses for such years, and gains (but not losses) realized with respect to the Offer cannot be treated as capital, even if a U.S. Holder holds the shares purchased pursuant to
the Offer as a capital asset.

An election to mark-to-market our shares would mitigate the adverse consequences resulting from PFIC
status. An election to treat us as a qualifying electing fund, however, would not be available to a U.S. Holder because we would not provide the information a U.S. Holder would need to make the election.

Backup Withholding. U.S. Holders should see Section 3 for a discussion of the application of U.S. backup withholding.

Non-Participation in the Offer

U.S. Holders of shares who do not participate in the tender offer should not incur any United States federal income tax liability in respect of
holding such shares as a result of the Offer.

THE U.S. FEDERAL INCOME TAX DISCUSSION SET FORTH ABOVE MAY NOT BE APPLICABLE DEPENDING UPON
A U.S. HOLDERS PARTICULAR SITUATION. HOLDERS SHOULD CONSULT THEIR OWN TAX ADVISORS CONCERNING THE TAX IMPLICATIONS OF THE OFFER UNDER

APPLICABLE FEDERAL, STATE OR LOCAL LAWS. NON-U.S. HOLDERS SHOULD ALSO CONSULT THEIR OWN TAX ADVISORS REGARDING THE TAX CONSEQUENCES TO HOLDERS WHO ARE NOT U.S. PERSONS.

15. Extension of the Tender Offer; Termination; Amendment

We expressly reserve the right, in our sole discretion, at any time prior to the Expiration Time and from time to time, and regardless of
whether or not any of the events set forth in Section 7 shall have occurred or shall be deemed by us to have occurred, to extend the period of time during which the Offer is open and thereby delay acceptance for payment of, and payment for, any
shares by giving oral or written notice of such extension to the Depositary and Paying Agent and making a public announcement of such extension. We also expressly reserve the right, in our sole discretion, if any of the conditions set forth in
Section 7 has occurred or is deemed by us to have occurred, to terminate the Offer prior to the Expiration Time and reject for payment and not pay for any shares not theretofore accepted for payment or paid for or, subject to applicable law, to
postpone payment for shares by giving oral or written notice of such termination or postponement to the Depositary and Paying Agent and making a public announcement of such termination or postponement.

Our reservation of the right to delay payment for shares which we have accepted for payment is limited by Rule 13e-4(f)(5) under the Exchange
Act, which requires that we must pay the consideration offered or return the shares tendered promptly after termination or withdrawal of a tender offer. Subject to compliance with applicable law, we further reserve the right, in our sole discretion,
and regardless of whether any of the events set forth in Section 7 shall have occurred or shall be deemed by us to have occurred, to amend the Offer in any respect, including, without limitation, by decreasing or increasing the consideration
offered in the Offer to holders of shares or by decreasing or increasing the number of shares being sought in the Offer.

Amendments to
the Offer may be made at any time and from time to time effected by public announcement, such announcement, in the case of an extension, to be issued no later than 9:00 a.m., New York City time, on the next business day after the last previously
scheduled or announced Expiration Time. Any public announcement made under the Offer will be disseminated promptly to shareholders in a manner reasonably designed to inform shareholders of such change. Without limiting the manner in which we may
choose to make a public announcement, except as required by applicable law, we shall have no obligation to publish, advertise or otherwise communicate any such public announcement other than by issuing a press release. In addition, we would file
such press release as an exhibit to the Schedule TO.

If we materially change the terms of the Offer or the information concerning the
Offer, we will extend the Offer to the extent required by the rules promulgated under the Exchange Act. These rules and certain related releases and interpretations of the SEC provide that the minimum period during which a tender offer must remain
open following material changes in the terms of the Offer or information concerning the Offer (other than a change in price or a change in percentage of securities sought) will depend on the facts and circumstances, including the relative
materiality of such terms or information; however, in no event will the Offer remain open for fewer than five business days following such a material change in the terms of, or information concerning, the Offer.

If (i)(a) we increase or decrease the price to be paid for shares beyond the price range, (b) decrease the number of shares being sought
in the Offer, or (c) increase the number of shares being sought in the Offer by more than 2% of the outstanding shares and (ii) the Offer is scheduled to expire at any time earlier than the expiration of a period ending on the tenth
business day from, and including, the date that such notice of an increase or decrease is first published, sent or given to shareholders in the manner specified in this Section 15, the Offer will be extended until the expiration of such period
of ten business days.

If we increase the value of shares sought in the Offer such that the additional amount of shares purchasable in the
Offer does not exceed 2% of the outstanding shares, this will not be deemed a material change to the terms of the Offer and we will not be required to amend or extend the Offer. See Section 1.

In the second quarter of 2007, the Board adopted a regular quarterly cash dividend program and authorized a $0.10 per common share quarterly
dividend. Following this authorization, the Company paid its shareholders a regular quarterly cash dividend from the second quarter of 2007 through the first quarter of 2014, and the Board steadily increased the authorized quarterly dividend from
$0.10 per common share to $0.30 per common share during this period.

Subsequently, after examining the Companys financial
performance and the market valuation of its shares, on April 28, 2014, the Board, as part of its goal to accelerate cash returns to the Companys shareholders, approved terminating such cash dividend program and instead utilize the
Companys cash to repurchase additional shares of the Companys outstanding common shares pursuant to the Companys $1.5 billion share repurchase program that it had previously authorized.

On February 21, 2017, at its telephonic meeting, the Board authorized a new three-year $1.5 billion share repurchase program that will
expire on February 21, 2020, which replaced the Companys prior share repurchase authorization that was set to expire on June 30, 2017. The current share repurchase program allows the Company and its wholly owned subsidiaries,
including HBL Swiss, to repurchase common shares, at such times and prices as determined by the Companys management, as market conditions warrant, and to the extent our distributable reserves are available under Cayman Islands law. During this
meeting, the Companys management and the Board evaluated various alternative strategies to execute the share repurchase program, including among other things by means of a tender offer and through open market purchases.

The Company did not repurchase any common shares in the open market during the year ended December 31, 2016. However, during the year
ended December 31, 2017 and the three months ended March 31, 2018, HBL Swiss purchased approximately 5.0 million shares through open market purchases at an aggregate cost of approximately $328.9 million, or an average cost of $65.62
per share.

In October 2017, the Company completed the Prior Offer and subsequently paid cash to repurchase and cancel a total of
approximately 6.7 million of its common shares at an aggregate cost of approximately $457.8 million, or $68.00 per share. In connection with the Prior Offer, the Company also provided a non-transferable contractual contingent value right for
each share tendered, allowing participants in the Prior Offer to receive a contingent cash payment in the event Herbalife is acquired in a going-private transaction (as defined in the contingent value right agreement filed as an exhibit with the
corresponding Schedule TO) within two years of the commencement of the Prior Offer.

Following the Prior Offer, the Companys
management and the Board have continued to evaluate the effectiveness of the share repurchase program and potential alternative methods to repurchase common shares, including among other things by means of a tender offer.

On February 27, 2018, the Board met telephonically with the Companys management and representatives from Gibson, Dunn &
Crutcher LLP, the Companys outside counsel, Morgan, Lewis & Bockius LLP, outside legal counsel to the Board, M. Klein & Company, financial advisor to the Board, and Moelis & Company, financial advisor to the Company,
to discuss, among other things, the merits of a potential self-tender offer. In this meeting, the Board authorized the Company to pursue a modified Dutch auction tender offer to purchase common shares for an aggregate cash purchase price of between
$450 million and up to $650 million. Further, the Board established a committee (the Committee) comprised of Keith Cozza, James L. Nelson and Richard P. Bermingham and delegated to the Committee the power and authority to review,
evaluate and make recommendations to the Board regarding the terms of a potential self-tender offer to repurchase common shares of the Company. On March 16, 2018, the Board, by unanimous written consent, updated the composition of the Committee
to remove Mr. Cozza and Mr. Bermingham from the Committee and designate Jeff Dunn, Jesse Lynn and James L. Nelson to be all the members of the Committee.

On April 12, 2018, the Board unanimously approved this Offer pursuant to the
recommendation of the Committee. In determining to proceed with the Offer, the Board evaluated the Companys operations, financial condition, capital needs, regulatory requirements, strategy and expectations for the future and believes that the
Offer is a prudent use of the Companys financial resources. The Board determined that it was in the best interests of the Company and its shareholders to pursue the Offer and authorized management to commence the Offer.

On April 17, 2018, the Committee met telephonically and, after discussing the proposed terms of the potential tender offer, approved the
final terms of the Offer.

On April 18, 2018, the Company commenced the Offer.

18. Miscellaneous

The Company has filed with the SEC a Tender Offer Statement on Schedule TO, which contains additional information with respect to the Offer.
The Schedule TO, including the exhibits and any amendments and supplements thereto, may be examined, and copies may be obtained, at the same places and in the same manner as is set forth in Section 10 with respect to information concerning the
Company.

This Offer to Purchase and accompanying Letter of Transmittal do not constitute an offer to purchase securities in any state in
which such offer is not permitted or would not be permitted pursuant to the laws of such state(s). If we become aware of any state where the making of the Offer or the acceptance of shares pursuant thereto is not in compliance with applicable law,
we will make a good faith effort to comply with the applicable law where practicable. If, after such good faith effort, we cannot comply with the applicable law, the Offer will not be made to (nor will tenders be accepted from or on behalf of) the
holders of shares in such state(s).

The number of common shares subject to the Offer and the price per share relate to the common
shares as outstanding on the date of the Offer. The Expiration Time is currently scheduled two days after the stock split distribution date (May 14, 2018) when, the Company expects to effect a two-for-one stock split as described in the
Companys 2018 proxy statement. Following the stock split, the Cash Purchase Price will be adjusted ratably to account for the increased number of common shares outstanding on a post-split basis. Shareholders should complete the Letter of
Transmittal (and any other documents used to tender common shares) specifying the number of common shares, and the cash purchase prices(s) per share, they are tendering in the Offer on a pre-split basis. If
nothing is so specified, the Company will assume the number of shares you are tendering is on a pre-stock split basis. See Instruction 5 of the Letter of Transmittal and Section 8 of this Offer to Purchase.

You should only rely on the information contained in this Offer to Purchase or to which
we have referred to you. We have not authorized any person to make any recommendation on behalf of us as to whether you should tender or refrain from tendering your shares in the Offer. We have not authorized any person to give any information or to
make any representation in connection with the Offer other than those contained in this Offer to the Purchase or in the related Letter of Transmittal. If given or made, any recommendation or any such information or representation must not be relied
upon as having been authorized by us, the Depositary and Paying Agent or the Information Agent.
